Answer:
nutrients are major determinants of plant growth and productivity in nature
Explanation:
Annie wants to have children, but she and her husband have been unsuccessful so far.
Do her cells in her ovaries need to go through mitosis or meiosis? Choose one, and
explain why.
Answer:
meiosis
Explanation:
The germ cells that enter meiosis become oocytes, the source of future eggs. Consequently, females are born with a finite number of oocytes arrested in the first meiotic prophase. Within the ovary, these oocytes grow within follicle structures containing large numbers of support cells. (i don't know if the explanation is correct but i know that it is meiosis)
They showed that adult cells could be reprogrammed to become cells with the properties of an embryonic stem cells
Answer: Kathrin Plath and William Lowry
Explanation:
Kathrin Plath and William Lowry and researchers at the University of California in Los Angeles(UCLA) were able to reprogram adult cells to become develop properties of embryonic stem cells which are very important as they can become any type of cell in the body which can have very important implications in medicine.
They did this by genetically altering the cells to enable them age backwards to a point where they were like the aforementioned stem cells.

Can you make this longer. The cause of the bee population to decline.
Answer:
Explanation of previously stated factors resulting in a declining bee population.
Explanation:
The user should submit further information on why the bee population is declining. My personal recommendation would be to introduce a reason and then explain it.
In response to your stated reasoning(s), assuming they are correct, this would be giving information such as: What can pesticides do to bees? What are some statistics showing habitat destruction. What do bees need to be nourished?
I would not recommend ending your answer with "and more".
By submitting this answer and referring to the work and resources given I trust you're in accordance with the Brainly Honor Code and I take no responsibility for any laws or rules broken with you using this platform.

Heriberto wanted to compare the gravity on the moon to the gravity on earth which statement below is correct
This question is incomplete; here is the complete question:
Herberto wanted to compare the gravity on the Moon to the gravity on Earth. Which statement below is correct?
The gravity on Earth is less than the gravity on the Moon.
The gravity on Earth is greater than the gravity on the Moon.
The gravity on Earth is equal to the gravity on the Moon
The gravity on Earth is the same as the gravity on the Moon.
The correct answer is The gravity on Earth is greater than the gravity on the Moon.
Explanation:
One of the factors that most affect the gravity (the force that makes objects move towards the center of a body) of planets like Earth or smaller bodies such as the moon is the mass. Indeed, if the celestial body is more massive or contains more mass the gravity force is stronger. Now, the mass of Earth is higher than the one of the moon. This makes the gravity of the moon weaker. Indeed, the gravity on Earth is 9.8 meters per square second, while the one in the moon is 1.62 metes per second, which is about 1/6th of the gravity on our planet.
10. Deafness in cocker spaniels is inherited. The allele for deafness (d) is recessive to the allele for hearing (D). Two cocker spaniels that are heterozygous for hearing are mated together. What is the chance that a puppy will be deaf?
Question 10 options:
0%
25%
50%
100%
Answer:
25%
Explanation:
If they are both heterozygous, it means they both have a Dd genotype. If you draw out a punnet square Dd x Dd you end up with the following possible genotypes for the puppy:
DD, Dd, Dd, dd
In order for the puppy to be deaf, it must be dd since deafness is recessive, which is 1/4 (25%)
The chance that the puppy will be deaf is 25%. The correct option is B.
What is allele?The term "allele" refers to the alternative form or versions of a gene. People inherit one allele for each autosomal gene from each parent, and we tend to categorize the alleles.
We usually refer to them as normal or wild-type alleles, or abnormal or mutant alleles.
If they are both heterozygous, they have the Dd genotype. As per the Punnett square Dd x Dd, one can see the the following genotypes for the puppy:
DD, Dd, dD, dd
Because deafness is recessive, the puppy must be dd, which is 1/4 of the population.
Thus, the correct option is B.

Please hurry!!!!!!What 2 criteria determine passive transport?
Answer:
The rate of passive transport depends on the permeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration, and/or osmosis.

R. Scientific errors are factors that could have contributed to the uncertainty in the outcome of your experiment. Could measurements have been more accurate? Could you have performed more trials? Could environmental factors, such as the lab's lighting or temperature, have had an effect? State these possible sources of error and analyze or estimate how much they may have affected your results.
Answer:
Yes.
Explanation:
Yes, measurements should be more accurate if these scientific error are removed. Yes, we must perform more trials in order to verify the experiment. Environmental factors, such as the laboratory's lighting or temperature, has a great effect on the experiment and can cause error. In this experiment the errors occur such as instrumental, environmental, procedural, and human. All these error causes inaccurate readings of experiment so greatly affect the experiment.
What are similarities and differences between the structures of DNA and RNA?
Answer:
The similarities and differences between DNA and RNA are given as follows:
Explanation:
Similarities:
Both are made up of nucleotides
Nucleotides are made up of nitrogenous bases, a pentose sugar, and the phosphate backbone.
Both DNA and RNA have four nitrogenous bases each - two purines two pyrimidines
Purine binds with pyrimidines
Differences
DNA uses the nitrogenous bases adenine, cytosine, thymine, and guanine whereas RNA uses adenine, cytosine, uracil, and guanine. Uracil lacks a methyl group on its ring
RNA contains the sugar ribose that has an extra -OH while DNA contains the deoxyribose sugar that has H at the 2 carbon.
DNA is double-stranded while RNA is a single-stranded
Under alkaline conditions, DNA is stable while RNA is not stable.

How are the circulatory systems in animals and plants alike?
A- Their circulatory systems move blood throughout the organism
B- Their circulatory systems transport nutrients to cells
C-Both plants and animals have a pulmonary circuit
D- All plants and animals have a heart
Answer:
I think B
Explanation:
The circulatory system is the method of transport in plants and animals. Animals must have nutrients and oxygen reach every cell in their body. Plants must have nutrients and carbon dioxide reach every cell in their "body." The circulatory system is how these things are carried around the living organism.

Explanation:
What might happen at the cellular level of the plant if there was no water available for photosynthesis?
Answer:
when water levels are low due to water stress, photosynthesis can slow or even stop, causing internal food supplies vital to other processes to diminish or disappear -- yellowing may also occur if photosynthesis stops completely.
Explanation:
If there was no water available for photosynthesis, the cellular level of the
plant will be affected negatively in areas such as shrinking of cells and
decrease in photosynthetic activities.
Plants require water to produce food in the process known as
photosynthesis. When there is no water the photosynthesis is slowed down
and the cells begin to shrink.
The shrinking of cells then results to the wilting and yellowing of leaves of the plant.
