Answer:
Hypotonic solution
Explanation:
The solution with lower solute concentration is referred to as hypotonic solution while the other with higher solute concentration is called as hypertonic solution.
Since the solution concentration on inside of the cell is lower than that of solution present on the outside the cell; the solution inside the cell is hypotonic.

Answer:
The scientists can attribute structural similarities to common ancestry.
Explanation:
In evolutionary biology, common ancestry or common descent illustrates how an array of species share a most contemporary communal ancestor. There is a huge proof of common ancestry of all forms of life on Earth. The common ancestry in between the organisms of various species originates at the time of speciation, in which establishment of new species occurs from a single ancestral population.
As one would expect, throughout the world there is a strong relationship between the quantity of energy a country uses and the size of its
Answer:
economy
Explanation:
Whichever country do we look at, there is a strong relationship between the quantity of energy that the country uses and the size of its economy. The more developed and the larger the economy of a country is, the more energy is demanded for the economy to be driven. This leads to high demand for certain natural resources that produce energy, as the industry needs power in order to function. We can easily see this if we take in consideration the biggest economies in the world, USA, China, Japan, Germany, UK, France, and then if we see how much energy each of them uses, so we will come to a conclusion that the biggest economies are the biggest users of energy.

What term do scientists use to describe all the different forms of life on Earth? landscape biodiversity environment ecosystem
Answer:
The term that scientists use to describe the different forms of life on earth is biodiversity.
Explanation:
Biodiversity means biological diversity, a term that refers to the large number of species -among animals and plants- that exist on the planet. This diversity or variety is due, in principle, to the different genetic expressions that have resulted from evolutionary changes over time.
Biological diversity is a factor that defines the different ways in which an ecosystem can be presented and the interactions that can occur between living organisms.
The term Biodiversity is a compound word that comes from the words biology and diversity, first used in 1986 and recognized by the International Convention on Biological Diversity.

The process in which plants draw water from their roots to their leaves where it evaporates into the atmosphere is called ____________.
A .evaporation
B. condensation
C. precipitation
D. transpiration
Why is transpiration important for plants?
A. It allows the plant to breathe.
B. It keeps the plant exercised.
C. It keeps plants from getting too dry
D. It helps to regulate their temperature.

D. capillaries; veins
Answer:
1.D
2.C
3.B
Explanation:
hope this helps
Answer:
1. D
2. D
3. B
Explanation:
The only possible answer for the first question is transpiration because precipitation is essentially rain (and all its forms), condensation is the collection of water, and evaporation is simply water in gas form -- thus making D the "odd one out".
For the second question, we know that transpiration is heavily dependent on stomata/guard cells. Exercise has nothing to do with this topic, and transpiration has very little to do with dryness (which makes B and C incorrect). Finally, plants do NOT breathe through transpiration. Instead, they breathe through plant (cellular) respiration (which eliminates A, leaving only D).
For the third question, we know that stomata/guard cells control a variety of cellular (and extracellular) activities in plants. When the stomata are closed, rates of transpiration decrease due to the inability of water to escape. When they are open, however, rates of transpiration increase and the plant loses more water. The most similar thing to that in the human body would have to be our pores, which open and close in response to stimuli (they release sweat when we're too hot, trigger the production of oils in our skin, etcetera). The other choices do not make much sense; for example, capillaries are used for distributing and receiving supplements from the soil and do not control transpiration.
Use logical reasoning and remember that stomata/guard cells control gas exchange and water loss. I recommend watching Hank Green's videos on plants if you are truly confused.

Which type of soil is most likely to be found in horizon E?
A. A layer of bedrock
B. A layer of decayed plant matter
C. A layer of parent material
D. A layer of pale, Sandy soil lacking clay and iron
Answer:
D. A layer of pale, sandy soil lacking clay and iron
Explanation:
The soil is complex, composed of multiple layers/horizons all of which have different characteristic that make every horizon to have its own special role in it. The horizon E is the third horizon from the top. This horizon is characterized by being mostly sandy, and because the water manages to go through it very easily it is a horizon in which there's heavy leaching going on. Because of the leaching, this horizon loses the clay, iron, and aluminium from it, thus they accumulate in the horizon below it. As a horizon it is very important, especially for the trees, as their root systems manage to develop very well in this horizon because it is loos and sandy.
Answer:
D. A layer of pale, sandy soil lacking clay and iron

What are the dated fossils called that help scientists to identify or date rocks or fossils?
Answer:
Index fossils
Explanation:
The index fossils are the fossils that come in very handy for the geologists when it comes to identifying or dating rock samples or other fossils. The reason for this is that the index fossils have already been dated. They are fossils that are very commonly found, wide dispersed, are easy to be identified, and are limited to only a certain geological period. These characteristics make them an excellent indicator for the dating of the rock layers in which they are found, or the fossils found in the same layers with them, without conducting further examinations.

Answer:
Archaebacteria are the prokaryotic anaerobic bacteria.
Explanation:
Archaebacteria are the prokaryotic bacteria. They live in an extremely harsh environment. They are different from the other bacteria with some characters like their habitat. Their cell wall don't have peptidoglycan like other bacteria. Archaebacteria are resistance to penicillin and some other antibiotics. These are of three groups such as methanogens, Halophiles, and thermoacidophiles.
Methanogens are methane-producing bacteria and used as fuel. Halophiles are found in saline water and heavy salt concentration. They contain red carotenoid pigment in the cell. So they appear red. Thermoacidophiles can live in extremely high temperatures and high acidity.
what structure attaches muscle to bone
Answer:
tendons
Explanation:
A tendon attaches muscle to bone, transmitting the force from the muscle contraction to allow body movement.
Explanation:The structure that attaches muscle to bone is called a tendon. Tendons are made of tough connective tissue and serve to transmit the force generated when a muscle contracts, allowing the movement of the skeleton. For a skeletal muscle to pull on a bone and create movement at a joint, it has specific attachment points; the origin is where the muscle attaches to the fixed (stabilized) bone, and the insertion is where the muscle connects to the bone that gets moved.
Which of the following is an example of maintaining homeostasis?
A. Drinking water
B. Learning math
C. Playing board games
D. Calling friends
Answer:
I think its A. Drinking water.
Drinking water is example of maintaining homeostasis.
Explanation:
Homeostasis is the ability of a system to remain in equilibrium in terms of temperature or to maintain other physiological features. Since the sweating is responsible for cooling down the elevated body temperature hence drinking water can help in maintaining homeostasis. Homeostasis is a state where the proper functioning of body can take place. If the body is out of homeostasis or equilibrium then the function of the body will not be able to execute properly.

why would imbalance hormone levels cause a male to be unable to reproduce
Answer:
Many Reasons
Explanation:
For starters, low T - or low Testosterone can lead to low libido, which may physically cause him not to want to reproduce. Low T can also have detrimental effects to the fidelity or health of sperm cells, as testosterone is necessary for the proper maturation of sperm. That means then, that at the cellular level if you have unhealthy sperm then they may not be able to fertilize an egg.

Which of the following are limiting nutrients ?
Water
Carbon
Nitrogen
Phosphorus
Answer:
Nitrogen and Phosphorus
Explanation:
When the function of a whole ecosystem is limited because of a nutrient , which is present in limited amount, it is called as a limiting nutrient. The organisms uptake water and carbon directly from the environment as it is abundant in nature. The nutrients like nitrogen and phosphorous are present in limited amount and moreover they are not present in the form that can be directly taken up by the organism.
Thus, Nitrogen and Phosphorous are limiting nutrients.

Which of the following is a major function of the cell membrane?
A. To surround and support organelles in eukaryotic cells
B. To receive and send messages between cells
C. To provide rigid support to plant cells
D. To combine amino acids into long chains to make proteins
The major function of the cell membrane is to provide a barrier around the cell, control substance movement via its selective permeability, and facilitate cell communication, making option B ('To receive and send messages between cells') the best answer. Hence the correct option is B.
The cell membrane's structure, primarily made of a phospholipid bilayer, allows it to be selectively permeable, controlling which substances can enter and leave the cell. It is involved in various functions including protecting and supporting the cell, and actively participating in the transport of materials. It also has the important role of facilitating communication and signal transduction, which means option B, 'To receive and send messages between cells,' best describes a major function of the cell membrane. It's also worth noting that the cell membrane encloses the cytoplasm and houses membrane proteins which may vary from one cell type to another, contributing to the diverse functions of the cell membrane in different cellular environments. However, while it does provide some support, option B is a more encompassing choice that includes this function as part of its role in cellular communication and interaction.
