What is the relationship between matter and energy in an ecosystem?
Matter and energy are cycled through the ecosystem.
how do homologous structures develop
Answer:
Explanation:
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor.the existence of homologous structures adapted to different purposes as the result of descent with modification from a common ancestor.

Compared with mitosis, the process of meiosis results in daughter cells
that are-*
Answer:
D haploid (n) with a smaller number of chromosomes than the parent cells
Explanation:
meiosis results in gametes which have half the number of chromosomes and are therefore diploid because they have one set only. that is because later, the two cells with half the chromosomes (egg and sperm) join together to make a diploid cell

Explanation:
A domestic cat has 38 chromosomes in its skin cells, while a dog has 78 chromosomes. How does this fact help to explain why dogs and cats cannot interbreed?
Answer:
The sex cells could not easily combine to form the body cells of an offspring because of the different chromosome number.
Explanation:
The fact that dog and cats cannot be interbreed because there is difference in the no. of chromosome.
What is interbreeding?
The act of mixing different species or varieties of animals or plants and thus to produce hybrids is called interbreeding.
Dogs have 78 no of chromosome which is similar to the lions and tigers but there is difference in the no of chromosomes which cannot produce viable offspring.

Protein breaks down into
Answer:
amino acids
Explanation:
Proteins ingested in the diet are digested into amino acids or small peptides that can be absorbed by the intestine and transported in the blood.
Answer:
Mostly into carbohydrates and fats.
Explanation:
"They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases" - Protein Digestion: Enzymes, Absorption, and Ways to Improve

If no energy is transferred, how much work is done?
Answer:
Explanation:The potential energy is converted to kinetic energy in the process. But I see no transfer of energy between the earth and the body.
And how does energy transfer takes place in case of negative work ? When a body is moved across a surface which has friction, the friction does negative work. Does it mean that a sort of energy transfer occurs between the surface (source) and the body (object
if glucose is in higher concentration outside the cell than inside, but the plasma membrane and other surface layers of the cell do not allow glucose to pass through, which is the most likely type of transport for glucose? and Why?
a simple diffusion
b Osmosis
c Facilitated diffusion via a gated channel
d Facilitated diffusion via an aquaporin
e Facilitated diffusion via an ion channel
Answer:
a
Explanation:
ok ok as you were saying you said it is hard for the glucose concentration in the body this also had to go out so but the plasma membranes and other surfaces layers cell layers of the layer of the soil do not allow to close glucose to pass through which is most likely type of transport type of transport for kids and you still said why it is because it gives energy to the body

Why is it necessary for the cell to grow and duplicate its DNA before the start of meiosis?
Answer:
Cells will duplicate or copy their DNA right before they divide. The process of cell division is called mitosis. Since the cell is dividing it needs two copies of its DNA - one is kept by the parent cell and the other is passed to the daughter cell. ... So this process of duplicating DNA is very important.

What causes water to runoff?
A) The sun heats up Earth's surface.
B) Water vapor condenses into water droplets.
C) Water does not soak into the ground.
D) There is a small amount of precipitation.
Explain why.
Answer: Runoff occurs when there is more water than land can absorb. The answer you’re looking for is C.
Explanation: The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds. ... Glaciers, snow, and rain all contribute to this natural runoff. Runoff also occurs naturally as soil is eroded and carried to various bodies of water.
What posture is a dog displaying if she is leaning away from your, body lowered, ears back, tail down, showing whites of her eyes and the corners of her mouth pulled back.
Answer: Fearful and worried posture
Explanation:
Since dogs cannot talk, their body languages are used to interpret whatever emotion or feeling they may be experiencing.
When a dog is afraid, she tries to look small. She lowers her body and and leans away so that her center of gravity is over her hind legs to make a quick retreat easy. She also puts her tail down and ears flattened back to her skull. Her eyes also look rounder than normal and she shows the whites of her eyes (whale eyes).
All these tell that a dog is scared and worried or feeling tense.
Answer:
Defensive Threat Posture
Explanation:
Whale eye (whites of eyes showing)
Tail down or fully tucked
Piloerection
Ears back or flatten against head
Pupils dilated
Corners of mouth pulled back
Body lowered
Body leaning backward
A defensive threat posture indicates a dog is being self-protective. This is seen in a dog who is fearful and would prefer to run away from the situation, but may bite if provoked or cornered. Stress signals were offered in the beginning, however ignored and the dog is showing extreme fear.

Proteins are the final products of the sequencing process that begins with cellular DNA information.
Explanation:
Proteins form structural and motor components in the cell as workhorses of the cell, and they serve as the catalysts for virtually every biochemical reaction in living things. This incredible array of features stems from a remarkably simple code that defines a greatly varied collection of structures.
