what does a root hair cell do
Answer:
Root hair cells (black arrow pointing at one of the root hair cells) are single tubular root cells. Their distinctive lateral elongation increases the surface of exchange between the plant's root system and the soil. The main function of root hairs is the uptake of water and nutrients from the rhizosphere.

which of the followimg could be reasons why popultion sizes may reach and maintaim plateaus? choose the three that apply
Will mark as brilliant answer
Answer:
Below :D
Explanation:
So basically, this question is asking what will cause a species' population to reach a point where it stops increasing.
Lets think about what can cause a lack of increase?
A decrease can cause this.
Or a slow in the rate of increase.
Now lets look at our selectable answers and see if any of them would fall under these two things.
First up is fewer deaths.
Well, fewer deaths basically means less of a decrease in population.
This is the opposite of decreasing the populatin count, and would instead raise it.
Next we have a limit in food supply.
This would cause a organism to starve and die.
So this would cause a decrease in population count.
So B is one of the answers
Next up is competition with other species.
When two species compete for a sort of resources, one massivly dies out due to outcompetion, and loses the resources needed to survive.
So this would also cause a large decrease in population count.
This makes C one of the answers
Next is increase in birth rates.
This would cause more organisms to be born of a species, basically increasing the population count.
This is the opposite of a decrease in population.
Next we have competition for space.
This is very similar to answer C, and the outcompeted species dies out due to lack of space.
So E is one of the answers
Now, the next answer seems viable, because major storms can kill off organisms, like hurricanes, earthquakes, and volcanos for instance.
However, as seen in many organisms over history, while these major storms kill of organisms, they can recover.
So although major storms decrease populations, they dont actually limit them.
In the end:
B is correct
C is correct
E is correct

different types of cells in the body have different organells depending on their main function. Considering this which type of cells would have the most mitochondria?
A. Red blood cells
B. Bone cells
C. Muscle cells
D. Nerve cells
E. Skin cells
Please help it’s biology!!!!!!
Answer:
25%
Explanation:
If a parent is heterozygous, it has 2 difterent alleles. Both parents are heterozygous for blood type A, so the genotype is AO. A masks the O because A is dominant over O, so A is the blood type.
Create a punnett square to find possible offspring
AA = Blood type A
AO = Blood type A
OO = Blood type O
There is 1 child out of 4 that have blood type O. So to find the percentage divide 1 and 4 and multiply by 100.
1÷4×100 = 25

en donde se produce La citocinesis
La citocinesis ocurre al final del ciclo celular después de la mitosis o meiosis. En la división de células animales, la citocinesis ocurre cuando un anillo contráctil de microfilamentos forma un surco de escisión que pellizca la membrana celular por la mitad. En las células vegetales, se construye una placa celular que divide la célula en dos.

6 reasons why Meiosis and mitosis are different (PLEASE HELP)
Answer:
Reasons why they're different :
Explanation:
1. Mitosis is reserved for somatic cells while meiosis is reserved for sex cells (gametes).
2. Mitosis results in identical cells , while meiosis results in genetically distinct cells.
3. Mitosis undergoes one round of cell division while meiosis undergoes two rounds of divison.
4. Mitosis results in diploid daughter cells, while meiosis results in haploid daughter cells.
5. Unlike mitosis, meiosis differs in males and females.
6. Mitosis creates a human cell with 46 chromosomes, while meiosis creates a human cell with 23 chromosomes.
When designing an experiment, you come up with the question: How does the amount you talk to a plant help it grow? Which would be the best hypothesis
Answer:
The correct answer is - "If you increase the amount you talk to plants, then they will grow taller"
Explanation:
A hypothesis is a proposed or assumed explanation for the natural system or problem. It forms on the pre-existed or known data or knowledge. A good hypothesis should have the ability to relate to dependent and independent variables.
In this case, the best hypothesis would be "If you increase the amount you talk to plants, then they will grow taller" as it relates to the dependent and independent variables that are the growth of the plant and talking to the plant respectively.

Answer:
The options are not complete, here are the remaining options from other websites.
d. divide uncontrollably and are immortal
e. have an extra set of chromosomes, which keeps them dividing.
The correct answer is divide uncontrollably and are immortal .
Explanation:
This because cancer cells are abnormal cells that divide uncontrollably and does not follow the normal cell cycle. abnormal cell that doesn't follow this cycle. Instead of them to die, the car continually reproduce more abnormal cells that can easily invade nearby tisssues. They can travel to all part of the lymph and body parts.
Describe TWO environmental consequences, other than those related to the loss of boreal forest habitat, that result from the extraction of bitumen or the transportation of synthetic oil to customers.
Answer: The greenhouse gas emissions from the extraction of bitumen and the use of large quantities of water.
Explanation:
Bitumen is a natural flammable organic matter formed from kerogen in the process of petroleum generation, which is soluble in carbon disulfide. Asphalt and mineral wax are examples of hydrocarbons which are part of bitumen. Conventional oil is extracted by wells while oil sands deposits are extracted using surface mining sectioning techniques, or are flowed to wells by in situ techniques that reduce bitumen viscosity by steam and/or solvents. So, unlike crude oil extracted in oil wells, bitumen requires an open-pit mining operation, in which large tracts are washed with a mixture of water and chemicals to separate the bitumen from a mixture of sand and clay.
Two consequences of this practice are:
The greenhouse gas emissions from the extraction of bitumen are larger than the extraction of conventional oil. The emissions produced contribute to enhance the greenhouse effect and cause global warming. The greenhouse effect occurs when certain gases retain part of the energy emitted by the earth's soil when heated by the sun's radiation. This phenomenon occurs naturally, and thanks to it, the average temperature of the Earth is about 14º C (57.2 °F). The problem occurs when these greenhouse gases increase in the atmosphere and the amount of energy that is not released into space also increases and, with it, the Earth's temperature. The extraction of bitumen from oil sands requires the use of large quantities of water, and even though water used here can be recycled, only a small amounts is returned to the natural cycle. Also, spills from the transportation of the oil could damage soils and waterways, increasing water pollution. This toxic water could get into surface.What is the purpose of mitosis?

What is a fixed allele?
A. An allele that is found on many genes
B. An allele present in all members of a population
Ο Ο
C. An allele that formed by adaptive radiation
O D. An allele that mutates with each generation
SUBMIT
PLEASE HELP
Answer:
The correct answer is - B. An allele present in all members of a population.
Explanation:
A homzygous variant or allele for all the members of a particular gene is a fixed gene and is the only variant that presents in all the population for that gene.
It takes place when there is all other alleles become extinct and only one remains. The allele frequency of this allele is always 1.00 in the population which means only one allele is present on the locus.

A geneticist wants to determine what mutation in a DNA molecule changed the structure of a specific protein. What would the scientist need to know before planning the investigation?
The normal sequence of bases that code for the protein
Whether the mutation was a substitution, insertion, or deletion
The total number of bases in the DNA molecule
How many thymine bases are in the DNA molecule
A mutation is any change in the sequence of DNA because of any reason such as deletion, insertion, etc. To determine the mutation in a DNA molecule changed the structure of a specific protein scientists should know the normal sequence of bases that code for the protein.
What is mutation?A mutation is a random change in the DNA sequence either due to insertion, deletion, or substitution.
By mutating a gene's code for making a protein, a variant can leads to a protein's improper functioning or to not being produced at all.
Scientists must mandatorily determine the normal base sequence of the protein code before investigating the mutation in the DNA sequence for a particular protein.
Thus, the correct option is A.

why is it important for plant's to store food?
Answer:
Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesis less. ... When they have extra food they store it in their seeds and when the seed grows it gets it's food from the plant until the plant is able to photosynthesis and produce its food.
Answer:
It's important for plants to store food, as food is a source of nutrition, which is necessary for survival. Rather than just eating the food, storing it is a good way to ensure nutrients during droughts or other harsh conditions that make it hard to find food.
