How would blood flow be affected if the aorta decreased in diameter?
Answer:
A decreased diameter means more of the blood contacts the vessel wall, and resistance increases, subsequently decreasing flow. The influence of lumen diameter on resistance is dramatic: A slight increase or decrease in diameter causes a huge decrease or increase in resistance.
How does a cell wall compare to a cell membrane?
The cell wall determines which materials can move in and out of plant cells, and the cell membrane provides structural support for animal cells only.
The cell wall provides structural support for plant cells, and the cell membrane determines which materials can move in and out of both plant and animal cells.

la cromatina esta formada por adn asociado a
Answer:
La cromatina es una sustancia dentro de un cromosoma que consiste en ADN y proteínas. El ADN lleva las instrucciones genéticas de la célula. Las principales proteínas de la cromatina son las histonas, que ayudan a empaquetar el ADN de una forma compacta que cabe en el núcleo celular. Los cambios en la estructura de la cromatina se asocian con la replicación del ADN y la expresión génica.

Which organelle converts sugars into energy?
A. lysosome
B. mitochondrion
C. nucleus
D. ribosome
The organelle that converts sugars into energy is the mytochondrion, which is the powerhouse of the cell, so the correct option is B. mitochondrion
Which organelle converts sugars into energy?The mitochondrion is often referred to as the "powerhouse" of the cell because it is responsible for generating energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration.
During cellular respiration, glucose (a sugar) and oxygen are metabolized within the mitochondria to produce ATP, which serves as the primary energy currency of the cell. The mitochondria are present in most eukaryotic cells and play a crucial role in energy production.

If Mendel had studied plants that reproduce asexually, he would not have been able to develop his laws of inheritance. Explain why. (hint: what's the main difference between sexual and asexual reproduction and why was this important when studying genes that get passed on?)
Answer:
He would not have been able to develop his laws of inheritance
Explanation:
if he had done it and work out his law on organisms that reproduce sexually it would have taken longer period than reproduction by asexual method .

The diagram below represents a stack of rock layers. Examine the diagram, and answer the question that follows. What do these layers and their fossils suggest about Earth's history?
Answer:
The farther down a layer with a fossil in it the farther back in earths history that organism lived.
Explanation:
Answer:
Layer T is older than 110 million years, and Layers R, X, and G are younger than 110 million years.
Explanation:
Because the principle of superposisiton states that younger layers of rock will be closer to the surface while older layers of rocks will be father to the surface therefore older

Deer are dependent on grass growing with ample
rainfall.
Deer do not adapt well in cooler environments.
There was significantly more hunting in 2011.

How can polyploidy cause speciation in plants?
Plants can sexually reproduce only when they are polyploid. Having the condition is normal in plants.
Plants can asexually reproduce or pollinate themselves. This allows polyploid individuals to reproduce.
Plants can repair polyploidy and obtain healthy cells. This allows plants to survive and reproduce.
Plants are not affected by polyploidy. Plants with the condition can reproduce normally.
Plants can asexually reproduce or pollinate themselves. This allows polyploid individuals to reproduce, this results develop cause speciation in plants, hence option B is correct.
What is polyploidy in plants?Polyploidy, which occurs when two or more genomes fuse within one nucleus, causes each cell to possess more than two pairs of homologous chromosomes.
Most angiosperms exhibit polyploidy, which is crucial for the survival of the agricultural crops on which people depend.
Three or more sets of homologous chromosomes are present in polyploid plants. These plants' increased chromosome count is the outcome of a genome duplication event.
Therefore, plants can asexually reproduce or pollinate themselves. This allows polyploid individuals to reproduce.

A. food pyramid
B. food chain
C. food web
D. food log
Hello!
Let's look at some definitions!
A food pyramid is levels of predators, in an pyramid shape to show the successive.
That does not match the definition your question provided, so we can move on.
A food chain is a series of animals who depend on each other for food/buisness.
Again, it does not match, this is a series, not an entire ecosystem.
A food web is a connection of food chains, which show the entire relationships of an ecosystem.
This definition is fairly close to the listed definition, lets keep this in mind.
A food log is a chart of what you eat each day.
Trick answer! This has nothing to do with the subject.
Given these choices, the correct answer is:
Food Web
