Why is sexual reproduction associated with meiosis? meiosis reproduces identical DNA meiosis is the complete process of sexual reproduction meiosis helps to generate variability meiosis produces gametes
Answer:
meiosis produced gametes
Explanation:
During sexual reproduction, meiosis generates genetic variation in offspring because the process randomly shuffles genes across chromosomes and then randomly separates half of those chromosomes into each gamete. The two gametes then randomly fuse to form a new organism.

2.) State the relationship between photosynthesis and cellular respiration.
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

How does the aorta compare in size to the other blood vessels near it?
Answer: Its wider and thicker than most blood vessels
Answer: The aorta is the largest blood vessel in the body. This artery is responsible for transporting oxygen rich blood from your heart to the rest of your body. The aorta begins at the left ventricle of the heart, extending upward into the chest to form an arch.
Blood vessels are the channels or conduits through which blood is distributed to body tissues. The vessels make up two closed systems of tubes that begin and end at the heart. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium.

Why is it important for your brain to control many functions automatically?
Answer:
The brain controls what you think and feel, how you learn and remember, and the way you move and talk. But it also controls things you're less aware of — like the beating of your heart and the digestion of your food.
Think of the brain as a central computer that controls all the body's functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part.
Explanation:
If you brain does not, or is unable to perform multiple tasks automatically, you could have trouble breathing on your own, your heart could have problems, even your thought process, movement, and digestion could malfunction. Which could cause a multitude of complications.

what would happen to the ecosystem in the terrarium if it were a closed system for energy
Answer:
It would mimic the behavior of the earth's atmospheric atmosphere where you have a water cycle and sunlight which aids photosynthesis.
Explanation:
A terrarium is a glass container that can be covered and opened at will. It can be used to grow a plants using soil.
When it is sealed, water evaporates onto the body of the glass and runs down the sides of the glass only to be evaporated again and the same process happens over and over again.
Because the plants are in a glass container, they can still access sunlight for photosynthesis.
Sometimes the glass is opened up for maintenance. Maintenance here refers to the removal of algae that sometimes forms on the inner walls of the terrarium. Sometimes, there is also need to add water to the ecosystem in the terrarium given that the water inside usually escapes via evaporation over time.

plant reproduction
Flowering plants reproduce sexually through a process called pollination. The flowers contain male sex organs called stamens and female sex organs called pistils. Cross-pollination happens when the wind or animals move pollen from one plant to fertilize the ovules on a different plant.

B)The population will no longer grow in size.
C)Death rate will increase, and birth rate will decrease until they balance each other out.
D)Birth rate will increase, and death rate will decrease until they balance each other out.
Answer:
✦ The birth and death rates will balance each other out for a net growth rate of zero.
✦ Death rate will increase, and birth rate will decrease until they balance each other out.
✦ The population will no longer grow in size.

a person has type B blood. What are all the possible blood types of his parents?
Answer:
It could be A and O, AB and A, AB and O or A and B.
Hope this helps! :)
A person has type B blood the possible blood types of his parents can be A x B, A x AB, O x AB, B x AB, AB x AB, B x O, B x B.
What is blood types?The four main blood types are A, B, AB, and O. Your blood type is determined by the genes your parents gave you.
Red blood cells with blood group A antigens have anti-B plasma antibodies. Plasma from people with blood group B contains anti-A antibodies and B antigens.
Blood group O has both anti-A and anti-B antibodies in the plasma but no antigens. Both A and B antigens are present in blood group AB.
A person with type B blood may have parents who have the blood types A x B, A x AB, O x AB, B x AB, AB x AB, B x O, or B x B.
Thus, these are some of the possible blood types.

The Paleozoic Era began approximately 550 million years ago and ended approximately 252 million years ago.
What is Paleozoic Era?The Paleozoic Era is a geological epoch that lasted about 541 million years and ended about 252 million years ago.
It is also known as the "Age of Invertebrates" because it witnessed the rise and dominance of numerous invertebrate groups, including trilobites, brachiopods, and ammonites.
From oldest to youngest, the Paleozoic Era is divided into six periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian.
Many significant events in the evolution of life on Earth occurred during this time period, including the Cambrian period's explosion of diversity, plant and animal colonization of land, and the emergence of reptiles and insects.
Thus, the answer is 550 million years ago.

describe how energy for the photosynthesis reaction is gained by plants (2)
please help
Answer:
Plzzzz answer fast......
The energy for the photosynthesis reaction is gained in the first stage of the reaction.
There are 2 stages in photosynthesis:
The light-dependent stageThe light-independent stageDuring the light-dependent stage, an electron in the molecules of chlorophyll gets excited and gets knocked off as a result of photon absorption. A molecule of water is split and the electrons released replace the one lost by the chlorophyll after traveling through the electron transport chain.
The energy from the traveling electron is used to reduce NADP+ to NADPH while the splitting of water to H and O means that a proton gradient is established between the stroma and the thylakoid lumen of the chloroplast. The electrochemical gradient thus created is used by ATP synthase to generate ATP from ADP.
The two chemicals, ATP and NADPH, are then utilized as energy sources for the light-independent reaction.
