What factors could decrease the rate of photosynthesis in a plant?
Answer: light intensity, carbon dioxide concentration and temperature i think- maybe
Explanation:
Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide, Increasing the light intensity will boost the rate of photosynthesis and for carbon dioxide even if there is plenty of light, the plant cant photosynthesise if there is insufficient carbon dioxide. and why temperature is because if it gets too cold the rate of photosynthesis will decrease, Plants cant photosynthesise if it gets too hot either
howw does an acquired mutation in a somativ cell gene leading to cancer develipment affact a persons abilty
Answer:
Cells become cancer cells largely because of mutations in their genes. Often many mutations are needed before a cell becomes a cancer cell. The mutations may affect different genes that control cell growth and division. Some of these genes are called tumor suppressor genes.

In __________ ribosomes can attach to the mRNA and begin translation even though transcription has not been completed.
Answer:
prokaryotes
Explanation:
All cells translate using ribosomes. Prokaryotic DNA lacks a nucleus, therefore translation happens before transcription. Simultaneous transcription and translation takes place.
What is translation in prokaryotes?In all cells, translation takes place at ribosomes. Prokaryotes translate DNA before transcription is finished because their DNA is not bound by a nucleus. Both transcription and translation take place at once. When a start codon on mRNA attached to a small ribosomal subunit is recognized by an initiator tRNA anticodon, translation can start. A second tRNA is recruited as the big ribosomal subunit joins the tiny subunit.
This is not conceivable in eukaryotes because translation takes place in the cytoplasm outside of the nucleus, whilst transcription takes place in a membrane-bound nucleus.

A model cell with damaged DNA was created to explain the importance of checkpoints in a cell cycle. The G2 checkpoint accidentally failed to work during experimentation. What do you think is the likely consequence of this failure?.
Answer: the consequenc of this failure is The cell continued to divide uncontrollably to create more damaged cells Which can lead to deadly diseases like cancer, breast cancer and many more
If the G2 checkpoint accidentally failed, then the cell will enter into division. The likely consequence of this failure is that the cell proliferates in an uncontrolled manner.
The cell cycle is controlled by checkpoints that regulate the progression through different phases of the cell cycle.
The G2 checkpoint acts to prevent the entry in mitosis of cells that have damages in its genetic material (DNA) in order to repair it.
When the cell undergoes failures in the G2 checkpoint control, the cell divides in an uncontrollable manner and thus generate groups of damaged cells (e.g., a tumor).

how are plant and animal cells similar in structure
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.

Explain what happens to the egg following fertilization, make sure you use the word "cells" and "chromosomes" in your answer.
Please HELP!!!
Answer:
The fertilized egg stays in the fallopian tube for about 3 to 4 days. But within 24 hours of being fertilized, it starts dividing fast into many cells. It keeps dividing as it moves slowly through the fallopian tube to the uterus. Its next job is to attach to the lining of uterus.

How does galaxy composition typically relate to the age of the stars in the galaxy? (1 point)
Star aging emits gas and dust, so galaxies with the youngest stars typically have the lowest proportions of dust and gas.
Star formation and the presence of young stars is common across galaxies, regardless of the proportions of dust and gas present.
Stars form from dust and gas, so galaxies with younger stars typically consist of higher proportions of dust and gas than other galaxies.
O Star formation consumes dust and gas, so galaxies where stars are oldest typically consist of higher proportions of dust and gas than other galaxies.
H
Galaxy composition typically relate to the age of the stars in the galaxy
through Stars being able to form from dust and gas, so galaxies with
younger stars typically consist of higher proportions of dust and gas than
other galaxies.
Components of a StarDustGasThe age of stars are usually determined through the amount of gas and dust
present in them. Stars burn gas to emit light and the younger ones have
more proportion of gas present than the older ones. The older ones have
less proportions due to more gas being burned over time.
The stated facts therefore makes option C the most appropriate.

Why is air temperature above land warmer than the air temperature above water in the same location during the summer?
Answer:
Sea breezes happen during the hot, summer days due t the unequal heating rate of land and water
Explanation:
Solar heating of the Earth’s surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces.

Match the digestive organ on the left with its function.
Answer:
pancreas: secretes digestive enzymes into the small intestine
esophagus: the place where peristalsis takes place
small intestine: area of the digestive tract where most nuturients are absorbed
stomach: area of the digestive tract that follows the esophagus
large intestine: area of the digestive tract where mostly water is absorbed
Explanation:
peristalsis: so the food can move down towards your stomach, independently of gravity
pancreas: helps your stomach become the ultimate weapon to destroy anything that gets in there with its enzymes
small intestine: it is really really long -> more time to absorb nutrients
large intestine: like a farm of bacteria, the most exotic things that somehow made it through all the way here are finally destroyed -> also, water absorbtion: your body wants to retain as much as possible, this is how and where stool formation takes place

Answer:
it's option C) clear sunny skies.
The type of weather associated with High pressure systems is : ( C ) clear sunny skies
High pressure systems have a greater amount of air pressure within their systems, when compared to its surroundings. Due to the presence of high air pressure within the system the air in the system is pushed into the surroundings.
Types of pressure systemsThere are two types of pressures systems and they are
High pressure system ; Possess more air pressure within the system Low pressure system ; Possess less air pressure within the systemAs the air leaves the high pressure system into the surroundings the system becomes clearer ( i.e clear sunny skies is evident in a high pressure system).
