How many capillary beds must a red blood cell pass through to move from an artery in the left arm to the left ventricle of the heart
Answer:
two capillary beds
Explanation:
Capillary beds are networks of capillaries that supply blood to the organs and/or areas of the body, in which nutrients and gas exchange (i.e., O2 and CO2) between red blood cells and tissues take place. Smaller arteries (i.e., arterioles) diverge into capillary beds composed of 10 to 100 capillaries, the smallest blood vessels in the body that connect the arterioles and the venules. Red blood cells usually flow into a capillary bed from a metarteriole (i.e., a microvessel that connects arterioles and capillaries). Red blood cells sometimes pass through two capillary beds before reaching the heart. The left heart ventricle is a muscle required for pumping red O2-rich blood out through the aortic valve into the aorta, whereas arteries are large blood vessels that branch into arterioles in order to carry blood to the capillary beds.

Recently discovered genetic evidence shows that multicellular land plants such as corn and wheat, are all of one lineage – they all arose from a single type of algae. Fossil evidence suggests that other types of algae did not have the needed complexity to move into terrestrial ecosystems. Explain at least 3 adaptations that algae would need to be able to survive on land.
Answer:
1) they would need a host or vessel to stay on and feed of of their body
2) they would need some for of reproduction in the host ( mitosis whatever the algae my use )
3) they would need to wisely choose there hosts and of what they feed on so there host doesn’t die quickly
I don’t know if this is what your looking for but these are 3 things that algae would need to live
Scenario 1:
Genetic engineering can be used to create more productive strains of farm animals used for milk and meat production. By adding genes to an animal’s DNA, the animal can be made to be more resistant to common infections. This can reduce the need to administer large doses of antibiotics to the animals.
Do you think that this type of genetic engineering should be pursued? Explain your answer. (5 points)
What are some possible impacts (positive and negative) of this type of genetic engineering on individuals, society, and the environment? (5 points)
Answer:
Yes.
Explanation:
Yes, this type of genetic engineering should be pursued in order to avoid decrease in death through infections or diseases as well as increase the production of milk and meat of that animals. With this genetic engineering, organisms have high resistance to diseases which decrease the cost of antibiotics. The positive effect of this genetic engineering is the increase in the resistance that leads to good health as well as productivity of organism.

Empty stomachs contract, causing both hunger pangs and the secretion of chemical messages that travel to the brain to serve as a signal to initiate feeding behavior. This is an example of ________. Group of answer choices
Answer:
How physiological mechanisms serve as the basis for hunger
Explanation:
Physiological mechanisms are able to provide explanations to body functions, events and outcomes. Such mechanisms could be altered voluntarily when there's the need to. Hunger is on example of such. When a person is hungry the muscles of the stomach contracts and messages are sent to the brain. This process is what tells the person thaat he needs to feed.

When individuals migrate, alleles can be transfered from one population to another population. This commonly referred to as
Answer:
Gene flow.
Explanation:
When individuals migrate, alleles can be transferred from one population to another population which is known as gene flow. Gene flow is also called gene migration, the introduction of genetic material through interbreeding from one population of organisms to another which changes the composition of the gene pool of the migrated population of organisms. This gene flow creates a new species that is different from previous population of organisms

The continental crust covers ____ of the earth's surface a. 40% b. 50% C. 60% d. 70%
Answer:
a. 40 percent
Explanation:
Answer:
a. 40%
Explanation:
The continental crust covers 40% of the Earth's surface.
At 25 to 70 km, continental crust is considerably thicker than oceanic crust, which has an average thickness of around 7–10 km. About 40% of Earth's surface area and about 70% of the volume of the Earth's crust is the continental crust. Most continental crust is dry land above sea level.
Organisms use glucose to store and transport energy.
True
False
Answer:
Glucose and ATP are used for energy by nearly all living things. Glucose is used to store and transport energy, and ATP is used to power life processes inside cells. Many autotrophs make food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose.
Explanation:
Most organisms use glucose and ATP for energy. ATP powers cells, and glucose stores and transports energy. Photosynthesis converts sunlight into glucose for many autotrophs.
What do organisms use to store and transport energy?All living things use ATP and glucose as energy sources. Energy is stored and transported by glucose, and cellular life functions are powered by ATP. Through the process of photosynthesis, which converts solar light energy into chemical energy that is stored in glucose, many autotrophs produce food.
Glycogen is the name given to this form of glucose that is stored and is composed of several linked glucose molecules. Glycogen is broken down to release glucose into the bloodstream, which is then used as fuel for the cells, when the body needs a sudden surge of energy or when the body isn't obtaining glucose from food.

Which of the following adaptations enables deciduous trees to produce more food?
a.
broad leaves
b.
thick bark
c.
leaf loss
d.
color change
The presence of broad leaves, which is present in Option A, enables deciduous trees to produce more food. Broad leaves have the benefit of increasing the photosynthetic rate, resulting in more food production.
What is the role of the leaves?Leaves are of many types, such as the neddle-shaped leaf and flat leaves, and all these leaves are adapted to different climatic conditions. The plants that are present in the tropical area have comparatively flat leaves compared to those that are present in the cold areas in order to control transpiration and heat.
Leafy plants that are green in color have chloroplasts and chlorophyll pigments that help in the photosynthesis process. Because the photosynthesis process produces food, if the leaf is green, it has more chloroplasts and thus produces more food.
Hence, The presence of broad leaves, which is present in Option A, enables deciduous trees to produce more food.
