Which of the following is a difference between arteries and viens?
arteries carry blood and veins carry only plasma
arteries do not have valves and veins do have valves
arteries are thin and veins are thick
arteries carry blood back to the heart and veins carry blood to the heart
The correct option is :
=》arteries do not have valves and veins do have valves.
Arteries don't have valves because back flow of blood isn't possible due to high pressure, but blood in veins doesn't have high pressure just like arteries, so to stop backflow of blood, veins have valves.

if pointed heads are dominant to round heads, which of the following genotypes could express a round phenotype
Answer:

A species of moth lived in a forest with a mixture of dark- and light-colored trees. The coloring of these moths is inherited. The dark moths were hidden from predators on the dark trees, and the light moths were hidden on the light trees.
When the light-colored trees were killed by a disease, the forest was suddenly made up almost entirely of dark trees. Generations later, almost all the moths had the dark coloring. Which of the following gives a correct explanation?
Answer: The light moths that survived did not mate and have offspring because they thought that their offspring would easily be seen and eaten by predators.
The light moths that survived had dark offspring because the change in the environment caused the parents to decide to have offspring that would do better in the changed environment.
The light moths saw that the dark moths were less likely to be eaten by predators, so they made themselves dark as well.
The dark moths were better hidden from predators, so more of them survived. Because dark parents outnumbered light parents, there were many more dark offspring than light offspring in the next generation.

Which process occurs by osmosis?
Select one:
a. plant roots absorbing water from the soil
b. the small intestine absorbing fatty acids into the blood
c. the small intestine absorbing glucose into the blood
d. plant roots absorbing mineral ions from the soil
Plant roots absorbing water from the soil occurs by osmosis.
Are roots absorbing water osmosis?Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
Do plants absorb water through osmosis?Plants absorb water and minerals salt from the soil with the help of root hairs. They absorb water by the process of osmosis. Osmosis is the movement of water molecules (solvent) from a lower concentration solution to a higher concentration solution through a semi-permeable membrane.

What can cause thermal expansion that results in a change in the density of ocean water?
a climate change
b freezing temperatures
c weathering and erosion
d addition of sediments
Answer:
Explanation:
B because Thermal expansion is caused when seawater expands because of the higher temperature of the water. Since the oceans absorb heat from the atmosphere, when the atmosphere becomes warmer so will the oceans. Warm seawater has a greater volume than cold seawater.
5. In 1928, Alexander Fleming noticed that a mysterious blue-green fungus had grown on some bacterial colonies that were known to cause strep throat. Upon closer inspection, he noticed that the bacterial colonies did not survive when introduced to the fungus. He questioned if something in the fungus stopped the bacteria from growing. Which steps in the scientific method are included in this story
Answer:
The steps that can be seen in this story are observation and the questioning phase, which can also be called elaboration of the problem.
Explanation:
The scientific method is a set of phases that are able to guide researchers to the creation of scientific knowledge, through an experiment. This method is essential for conducting scientific research, allowing an experiment to be managed in a way that promotes answers to scientists' questions. The scientific method presents the phases called observation, questioning (or elaboration of the problem), elaboration of hypotheses, experimentation, analysis of the results and conclusion.
In the story shown in the question above, we can see the phases called observation and questioning. The observation takes place the moment Fleming noticed a fungus capable of growing on colonies of bacteria that cause throat infections, killing them. This observation made him enter the questioning phase, when he wondered if the fungus was able to prevent the growth of these bacteria.
Which cell division phase is shown in the image?
A) telophase

C) prophase
D) anaphase
