Plant and animal cells, while both eukaryotic, each have distinguishing characteristics. For example, plant cells contain chloroplasts, while animal cells do not. Which statement BEST elaborates on the reason for this difference?
A) Chloroplasts are needed for plant cells to rid themselves of waste. Animal cells do not produce any waste.
B) Chloroplasts help plants make their own food by converting light energy. Animals do not make their own food.
C) An animal cell has a cell wall, while a plant cell does not. Instead, chloroplasts line the outside of plant cells.
D) The DNA in an animal cell is housed in a nucleus, but plant cells do not contain nuclei; it is stored in chloroplasts.
Answers
The right option is; B) Chloroplasts help plants make their own food by converting light energy. Animals do not make their own food.
Plant and animal cells are eukaryotic cells (cells that have a definite nucleus and membrane bound organelles). The two cells are similar structurally, and functionally, but a few significant differences exist in each of them. Plant cells have chloroplasts (organelles that contain chlorophyll which absorbs sunlight) it uses to produce its food though photosynthesis. Animal cells do not have chloroplast. It uses mitochondria (an organelle that produces energy through respiration) to produce most of the cells energy from food. Mitochondria is also present in plants cells but it does not have the same function in plant cells.
What can happen when you have taken much more than the normal amounts of vitamins?
Answers
You can get sick from certain vitamins because your body wont be able to digest all of them, causing negative affects on your organs.
You can also just have nothing negative happen. For example, taking an extremely high dose of vitamin D3 would most likely not hurt you, however after a certain point you would not gain anything from it.
Answer:
Taking vitamins is a daily routine that has millions of people around the world. However, taking too many vitamins can lead to an overdose and be dangerous to health.
Explanation:
For example, water-soluble vitamins (vitamin B1, B2, B3, etc.) are excreted from the body and are not stored in the tissues. However, an overdose of some of these vitamins can induce side effects, such as irreversible nerve damage, or liver damage.
Meanwhile, fat-soluble vitamins (vitamin A, D, K, etc.) do not dissolve in water and can be stored in your body's tissues. Due to the accumulation of these vitamins, they are likely to produce toxicity or harmful effects much more than water-soluble vitamins.

Answers
Multi cellular organisms have larger and more effective therefore have a very long life span instead of a uni cellar organisms
Multicellular organisms have many cells that are grouped into different levels of organization. They are larger in size, more efficient and live longer than unicellular organisms.
What are Multicellular organisms?
A multicellular organism is an organism that consists of more than one cell. A multicellular organism is composed of many cells that are integrated and independent to varying degrees.
Multicellular organisms evolved together
1. By cellular specialization
2. By division of labor
3. Cells become efficient at a process
4. To become dependent on other cells for the necessities of life.
Humans, animals, plants and fungi are multicellular organisms that are very large in size and very complex and intricate in their structure as well as structure.
Thus, Multicellular organisms have many cells that are grouped into different levels of organization. They are larger in size, more efficient and live longer than unicellular organisms.

A: light energy

C: chemical energy
D: carbon monoxide
Answers
panting
shade seeking behaviour- to reduce radiation exposure
migration- to move to more suitable climates
curling up- reduce surface area to volume ratio
others include structual changes (you can not change this)
large size- for low surface to volume ratio
round shape/short extensions- low surface to area volume ratio
then you have physiological changes this is done by either the hormone (endocrine) system or nervous system
vasioconstriction- reduce blood flow to extemeties
shivering- increase metabolic heat produced
as you can see these adaptions are used to create a negative feedback.What this means is it is the oposite to the stimulas. For example if you get cold(stimulas) you may shiver which creates heat and warms your body( the opposite effect of being cold and thus the reverse to the stimulas)
note there is some that create positive feedback as well.

Given two areas with equal sunlight and available water. Area I has a high amount of atmospheric carbon dioxide while Area II has a low amount of atmospheric carbon dioxide.
How does the rate of photosynthesis in Area I compare to that in Area II?
Atmospheric carbon dioxide has no effect on the rate of photosynthesis.
The rate of photosynthesis increases with a decrease in carbon dioxide.
The rate of photosynthesis increases with an increase in carbon dioxide.
The level of carbon dioxide increases with the level of available oxygen.

What are the four functions of the digestive system?
Answers
The digestive system involves all organs responsible for digestion. The four functions of the digestive system are digestion, absorption, excretion and assimilation.
What is digestion?Digestion is the breakdown of complex food materials into their simplest form, which is done by digestive system.
The main functions of digestive system are:
Digestion: breakdown of food.Absorption: The absorption of simple food into blood.Assimilation: movement of digested food molecules into the cells and are used. Excretion: the elimination of waste materials.Thus, these are the four functions of digestive system.

Explain why the size of your muscles is the is partly an acquired trait and partly dependent on DNA
Answers
It is an acquired trait because you could train your muscles to become bigger. When you train, for example resistance training, your muscle produces more myofilaments which increases their diameter. This is why you develop large muscles when you train.
Hope this helped!
Answer:
The size of the muscle is partly dependent on the DNA and exercise.
This is because DNA traits is actually responsible for how a muscle formed in the body. This trait is usually gotten from the parents of the offspring.
In the same vein, exercises can also be responsible for the size of an individual’s muscle. Exercises help in the expansion and building of muscle tissues which makes it bigger.

The Aleutian Trench is an area where the oceanic Pacific Plate is converging with the continental North American Plate. What can you conclude is happening in this area?
Answers
Final answer:
In the Aleutian Trench, subduction of the Pacific Plate beneath the North American Plate causes frequent earthquakes and volcanic activity, and is part of the seismically active Ring of Fire.
Explanation:
The Aleutian Trench is a region where the oceanic Pacific Plate is converging with the continental North American Plate. In this area, a process called subduction is occurring, where the denser oceanic plate is sliding beneath the less dense continental plate. This subduction leads to frequent earthquake and volcanic activity due to the melting of the subducted plate that forms magma, which can then rise to the surface to create volcanic cones. Additionally, the subduction zone in the Aleutian Trench area is part of a larger zone known as the Ring of Fire, characterized by high seismic activity and numerous volcanoes encircling the Pacific Ocean.
