How do hox genes allow for a large variety of animal forms?
Answer:
Hox genes are space-temporally expressed and thus play a major role in determining body organization during embryo development of animals
Explanation:
The Hox genes are evolutionarily conserved genes that encode major transcription factors during animal development, which are involved in the expression of target genes that regulate the formation of different parts of the body along the anteroposterior body axis. These genes contain an evolutionarily conserved DNA sequence called the homeobox. Hox genes are often organized in clusters that are space-temporally (sequentially) expressed during animal development, thereby inducing the formation of specific structures in the correct places of the body. The co-linear expression pattern of these clusters functions to ensure a normal developmental fate along the anteroposterior axis.
why are vitamins important to enzymes and what this relationship is called?
The activity of some enzymes requires vitamins. This is because vitamin derivatives contribute to the biochemical mechanisms of these enzymes. These vitamin derivatives belong to a class of molecules known as cofactors, which are organic molecules (called coenzymes) or metallic ions, that assist in the catalytic activity of an enzyme.
How did humans selectively breed dogs from the grey wolf?
Answer:
hope it help u
Explanation:
Dogs were probably domesticated by accident, when wolves began trailing ancient hunter-gatherers to snack on their garbage. Docile wolves may have been slipped extra food scraps, the theory goes, so they survived better, and passed on their genes. Eventually, these friendly wolves evolved into dogs
Answer: All modern dogs are descendants of wolves, though this domestication may have happened twice, producing groups of dogs descended from two unique common ancestors. ... Rather, say some experts, dogs may have exploited a niche they discovered in early human society and got humans to take them in out of the cold.

Answer:
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct. Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Plants help humans survive by giving out carbon dioxide to oxygen through this proccess that helps us to breathe.

Answer:
Aquitard
Explanation:
The Rain is Precipitation. So eliminate
The light blue is groundwater/aquifer. So eliminate
The brown is rock. So eliminate
The correct answer is aquitard. Aquitard prevents participation and filters the rain to become groundwater, which is stored in the aquifer.\

There are many technologies that reduce the amount of carbon emissions into our atmosphere. Identify some examples of these technologies.
Answer:
Biomass Energy
Explanation:
Biomass energy is energy generated or produced by living or once-living organisms. The most common biomass materials used for energy are plants, such as corn and soy, etc. The energy from these organisms can be burned to create heat or converted into electricity.

Research and identify which plants on earth are the most abundant in biomass and the ecosystem(s) in which these plants can be found. Discuss how varying carbon dioxide levels can affect the growth of plants, that affecting the levels of biomass.
Answer:
Trees and grass have the most abundant biomass. Among trees, pines are the most abundant in biomass. Pines are found in the terrestrial biome of coniferous forests. Grass is commonly found in the grassland biome.
Plants grow through a process called photosynthesis. This process uses carbon from the air to build tissue in plants. So increased levels of carbon dioxide in the air should mean better plant growth. However, a new study published in the Global Change Biology journal says that increased carbon dioxide levels in the atmosphere make it difficult for plants to absorb nitrogen. This nutrient is essential for plant growth. The researchers of the study looked at the effect of increased carbon dioxide levels in many ecosystems, including grasslands and forests. The researchers concluded that as carbon dioxide levels in the atmosphere increase, the concentration of nitrogen in plants decreases. Lower nitrogen amounts decrease the plant’s protein levels and ability to grow.
Increased carbon dioxide also means that plants need more water and fertilizer to grow. Inadequate rainfall and supply of fertilizers may not match the level of increased carbon dioxide received by plants. Thus, increased carbon dioxide can hamper the growth of plants.
Explanation:
This is edmentum sample answer so change it up
Answer:
Trees and grass have the foremost copious biomass. Among trees, pines are the foremost inexhaustible in biomass. Pines are found within the earthly biome of coniferous woodlands. The grass is commonly found within the meadow biome. Plants develop through a preparation called photosynthesis. This preparation uses carbon from the discussion to construct tissue in plants. So expanded levels of carbon dioxide within the discussion ought to cruel better plant development. Be that as it may, a modern think about distribution within the Worldwide Alter Science diary says that expanded carbon dioxide levels within the environment make it troublesome for plants to retain nitrogen. This supplement is basic for plant development.
The researchers of the consideration looked at the impact of expanded carbon dioxide levels in numerous biological systems, counting prairies and timberlands. The analysts concluded that as carbon dioxide levels within the climate increment, the concentration of nitrogen in plants diminishes. Lower nitrogen sums diminish the plant’s protein levels and capacity to grow. Increased carbon dioxide implies that plants require more water and fertilizer to develop. Lacking precipitation and supply of fertilizers may not coordinate the level of expanded carbon dioxide gotten by plants. Hence, expanded carbon dioxide can obstruct the development of plants.

How is upwelling important for marine organisms?
Answer:
Because the deep water brought to the surface is often rich in nutrients, coastal upwelling supports the growth of seaweed and plankton. These, in turn, provide food for fish, marine mammals, and birds. Upwelling generates some of the world's most fertile ecosystems.
Explanation:
Answer:
Upwelling is very important for marine organisms because these nutrients fertilize surface waters, encouraging the growth of plant life. Upwelling plays an important role in the movement of marine animals.

If a molecule is to large or polar and cannot easily diffuse into the cell, it is
considered to be
to the membrane.
permeable
impermeable
hydrophilic
phospholipid
Answer:
hydrophilic
Explanation:
Large polar or ionic molecules, which are hydrophilic, cannot easily cross the phospholipid bilayer. Charged atoms or molecules of any size cannot cross the cell membrane via simple diffusion as the charges are repelled by the hydrophobic tails in the interior of the phospholipid bilayer.

Please I beg you help me. Compare solids,liquids, and gases on the molecular level
Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
Answer:
The compression of solids is difficult, liquids are nearly incompressible but gases can be easily compressed.
Explanation:
molecular arrangements of solids is regular and close, but liquids have irregular and sparse molecular arrangement. Gases too also have more random and sparse arrangements of molecules.

How does bursting of animal cells take place
Answer:
Swelling and bursting of cells is also known as lysing. This happens when the concentration of solutes inside the cell is greater than the concentration of solutes outside the cell. It has to do with diffusion and osmosis. A high solute concentration relates to a lower water concentration. Since molecules like to diffuse from areas of high concentration to areas of low concentration, water will rush into the cell where the water concentration is lower causing it to swell and lyse.

True or False- Tsunamis are usually not a single wave, but a series of waves.
No Files or Links Plz
Answer:
A tsunami is a series of waves. Often the initial wave is not the largest. In fact, the largest wave may not occur for several hours. There may also be more than one series of tsunami waves if a very large earthquake triggers local landslides, which in turn trigger additional tsunamis.
Answer:
True
Explanation:
Tsunamis can in fact be a series of waves.
