Explain how these features make it easier for reptiles to live on land:
-Fingers with claws
-Eyes covering the eyes
- Horn scales on the body
- Spongy lungs
Explanation:
1. The presence of fingers with claws makes it easier for reptiles to cling on rough surfaces successfully. An example of this is the Gecko lizard.
2. Eyes covering the eyes of reptiles improves their vision so they can see objects from afar.
3. Horn scales on the body is commonly found in crocodiles, this scales are very helpful in preventing external injury on their bodies.
4. Spongy lungs are necessary for successful respiration, without the spongy nature of the lungs, air (oxygen) passage would be difficult for them.

butterflies taste with their feet, while humans taste with their tongues. in this way, butterfly feet and human tongues are ------------ structures
Answer:
analogous
Explanation:
They share the same function but have different evelutionary origins.
Final answer:
Butterfly feet and human tongues are analogous structures in biology.
Explanation:
This question can be easily answered by having basic understanding of the concepts of functionality and usage and the application of the same.
In biology, butterfly feet and human tongues are analogous structures. Analogous structures are similar in function and appearance but do not share an evolutionary history. While butterflies taste with their feet, humans taste with their tongues. Both butterflies and humans have structures that allow them to detect and interpret taste, but the specific anatomical features and mechanisms differ.
Therefore, butterfly feet and human tongues are analogous structures in biology
Which sentences describe the differences between photosynthesis and cellular respiration?
Check all that apply.
Cellular respiration uses oxygen as a reactant and photosynthesis does not.
Cellular respiration produces glucose and photosynthesis does not.
Cellular respiration produces excess ATP and photosynthesis does not.
Cellular respiration stores energy from the Sun in glucose molecules and photosynthesis does not
Cellular respiration is performed by consumers and photosynthesis is not.
O Cellular respiration releases energy from glucose molecules and photosynthesis does not.
Answer:
A, C, E, F. Are the answers :p
Explanation:
Trust me, Thank me later :)
Final answer:
Photosynthesis and cellular respiration serve opposite functions in the energy cycle. Photosynthesis creates glucose and oxygen from sunlight, which are then used by cellular respiration to release energy, producing ATP and emitting carbon dioxide and water.
Explanation:
The differences between photosynthesis and cellular respiration include their distinct roles in the energy cycle. Photosynthesis uses sunlight to create glucose and oxygen, which are then used in cellular respiration. Cellular respiration releases energy by breaking down glucose in the presence of oxygen, which results in producing ATP and emitting carbon dioxide and water as byproducts. One of the key differences is that photosynthesis stores energy from the sun within glucose molecules, while cellular respiration releases the stored energy from glucose to produce ATP, powering cellular activities.
Therefore, the following sentences describe the differences between photosynthesis and cellular respiration:
Cellular respiration uses oxygen as a reactant while photosynthesis produces it.
Cellular respiration releases energy from glucose molecules which is used to create ATP, a process not performed by photosynthesis.
Cellular respiration is primarily performed by consumers, organisms that cannot produce their own food, unlike photosynthetic organisms that can produce glucose.
The incorrect statements include that cellular respiration produces glucose (which is actually produced by photosynthesis), and that cellular respiration stores energy from the sun in glucose molecules (which is a function of photosynthesis).

Which process is shown in the diagram?
A. Cellular respiration
B. 02-CO2 cycle
C. Transpiration
D. Photosynthesis
The process shown in the diagram is Photosynthesis (option D)
What is photosynthesis?
Photosynthesis stands as an important process by which green plants, algae, and certain bacteria harness light energy, usually from the sun, and convert it into chemical energy. This intricate conversion unfolds within the chloroplasts of plant cells, chiefly employing chlorophyll, a light-absorbing pigment.
Within photosynthesis, carbon dioxide (CO2) sourced from the atmosphere and water (H2O) amalgamate under the influence of light energy, yielding glucose (a sugar variant) and oxygen (O2) as consequential products.
Answer: if photosynthesis is not an option its O2-CO2 cycle
In some cattle, the genes for red hair and for white hair are codominant. Cattle with alleles for both red and white hair have both red and white hairs. This condition is referred to as roan.
What is the probability, expressed as a ratio, of a white cow and a red bull having an offspring with the heterozygous genotype?
A. 1 homozygous white : 1 homozygous red : 1 heterozygous
B. 3 homozygous white : 1 homozygous red : 0 heterozygous
C. 0 homozygous white : 0 homozygous red : 1 heterozygous
D. 1 homozygous white : 1 homozygous red : 0 heterozygous
Plz help :((((
Answer:
Explanation: There is more than 1 pattern of inheritance that also is an example of lack of dominance. In this situation, if the resulting phenotype exhibits both of its parents traits, the offspring phenotype is most likely going to be the result of codominance

Which best describes the purpose of a fever?
to make the body too hot for the bacteria to live
to make the body too cold for the bacteria to live
to stimulate lymphocytes to make antibodies
to stimulate an increased production of sweat
The statement which best describes the purpose of a fever is that it stimulates lymphocytes to make antibodies. Thus, the correct option for this question is C.
What is Fever?Fever may be characterized as a type of circumstance in which the body temperature of an individual may rise as compared to the average temperature, i.e. 98.6°F (37°C).
You get a fever because your body is trying to kill the virus or bacteria that effectively caused the infection. Most of those bacteria and viruses do well when your body is at its normal temperature.
But if you have a fever, it is harder for them to survive. Fever also activates your body's immune system in a manner via stimulating lymphocytes to make antibodies.
Therefore, the correct option for this question is C.

Why were the researchers surprised to find out how old the remains of the hobbit were ?
Answer:
The biggest surprise came when the scientists dated the remains to only about 18,000 years old. This small species of human existed at the same time aş Homo sapiens, the species that modern human beings belong to. ... This supports the idea that the hobbits are actually a separate species.
Explanation:
Final answer:
The age and physique of Homo floresiensis were surprising because they displayed both ancient and modern human features and were thought to show complex behaviors despite their diminutive size and brain, leading to theories of island dwarfing.
Explanation:
The researchers were surprised to find out how old the remains of Homo floresiensis, also known as "the Hobbit", were because these remains challenged previous conceptions of human evolution. Not only was the species dated to approximately 100,000-60,000 years ago, which overlaps with the existence of modern humans, but their small stature and tiny brain volume were unexpected for that time period. The discovery of Homo floresiensis in the Liang Bua cave also showed evidence of sophisticated behaviors like the use of fire for cooking, which suggests complex cognitive abilities despite their small brain size. This combination of ancient dating and unexpected physical characteristics led to theories of regional evolutionary adaptations like insular dwarfing, which posits that limited resources on the island of Flores favored smaller body size over time.

During a lunar eclipse, the moon turns dark
due to the deviation of the sun's rays
caused by Earth's atmosphere.
A lunar eclipse occurs when the Moon enters Earth's shadow, with both celestial bodies and the Sun aligned.
During a lunar eclipse, the Moon passes into the shadow of the Earth. This happens only when the Sun, Earth, and Moon are aligned with the Earth in the middle, meaning the Moon is in a full phase. While entering the darker part of Earth's shadow, known as the umbra, the Moon's brightness diminishes and may take on a reddish color.
The shadow of Earth can cover about four full moons at the Moon's average distance, which explains the total coverage during a lunar eclipse. Unlike a solar eclipse which is only visible from specific places on Earth and involves the Moon casting a shadow on Earth, a lunar eclipse can be seen by anyone on the night side of Earth as the Earth casts a shadow on the Moon.
As the Moon goes deeper into Earth's shadow, the curved shape of the shadow becomes apparent, indicating Earth's spherical shape. The distinct red hue observed during a total lunar eclipse is due to the Earth's atmosphere filtering out blue and green light and bending the remaining light towards the Moon, a phenomenon also seen during sunsets.

A habitat can keep only a certain number of plants and animals alive. Changes in a habitat can affect the survival of plants and animals.
Choose each correct statement by clicking on it.
Clearing land to build homes or buildings changes a natural habitat and can force animals to move to another location to survive.
Fires, hurricanes, volcanoes, and earthquakes are examples of natural habitat changes that occur rapidly.
Changes in temperature or amount of rainfall(drought or flood) are examples of slow habitat changes that occur naturally.
Soil erosion is an example of a slow habitat change that occurs naturally and leads to the survival of fewer plants.
The development and use of farmland does not change the habitat of plants that naturally grow in an area.
When other animals or plants move into a habitat, they change the habitat by taking up needed space and food.
Extinction (loss of an entire group of organisms) can occur if animals or plants cannot adapt to changes in their habitat.
Answer:
all of them are correct except for "the development and use of farmland does NOT change the habitat of plants that naturally grow in an area"
Explanation:
This is not true because for farmland, farmers clear hundreds of trees in order to have flat land for cattle. They also clear plants for growing food as well but this is less catastrophic than the huge amount of land cleared for cattle.
Final answer:
The correct statements regarding habitat destruction effects on plants and animals include how both natural and human-induced changes can force animals to relocate, alter ecosystems, and potentially lead to species extinction. Incorrectly, the development of farmland also changes the habitat, contrary to one of the statements.
Explanation:
The question revolves around the concept of habitat destruction and its consequences on the survival of plants and animals. Here is a clarification of each statement:
Clearing land to build homes or buildings changes a natural habitat and can force animals to move to another location to survive - Correct. This is an example of human-induced habitat destruction.Fires, hurricanes, volcanoes, and earthquakes are examples of natural habitat changes that occur rapidly - Correct. These are natural disturbances that can significantly alter habitats.Changes in temperature or amount of rainfall (drought or flood) are examples of slow habitat changes that occur naturally - Correct. These gradual changes can affect habitat suitability over time.Soil erosion is an example of a slow habitat change that occurs naturally and leads to the survival of fewer plants - Correct. It affects the soil's fertility and structure, essential for plant growth.The development and use of farmland do not change the habitat of plants that naturally grow in an area - Incorrect. Conversion of land to farmland changes the natural habitat and can prevent the growth of native plant species.When other animals or plants move into a habitat, they change the habitat by taking up needed space and food - Correct. Invasive species can outcompete native species for resources.Extinction (loss of an entire group of organisms) can occur if animals or plants cannot adapt to changes in their habitat - Correct. The inability to adapt can lead to extinction.What are stem cells?

If photosynthesis and cellular respiration form a cycle, why do plants need to continually take in carbon dioxide,
oxygen, and water from the environment?
Answer:
The glucose(from cellular respiration) is turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
hope this helped :)
Explanation:
Answer:
Plants release excess oxygen, carbon dioxide, and water back into the environment. They don’t store them indefinitely. So, they continually need to take in these elements.
