Draw a model that correctly illustrates cellular division and differentiation in stem cells...
What should I draw?
Answer:
I dotnt know that but you can do that
Cellular division (Mitosis) is the biological process whereby a parent cell breaks itself into different parts called daughter cells.
This process is important because it helps to divide cells so that they can:
Experience growth Repair broken cells Reproduce, etc
Cellular differentiation is the process of a cell going from one form to a more specialized cell.
A good example of this is the process of a fetus being formed from a single celled zygote.
Attached below is an image of cell differentiation and cellular division.
What is the role of pollen in making new plants?
A
Pollen fertilizes the ovule, which becomes a seed. Seeds become new plants.
B
Pollen makes fruit turn into new plants.
с
Pollen makes it easier to get seeds out of fruit so that they can grow.
D
Pollen is what makes fruit taste good, so animals will eat it and spread seeds.
What is it????
Answer:
I think its D.
Explanation:
Pollination allows plants to improve genetic diversity within their species and, in some cases, plants will cross-pollinate with other flower varieties. This creates a heartier, more genetically diverse plant population and sometimes drives a mutation that results in a new species or hybrid.

2. What are the three examples Arroyo gives for how we can prepare for the
massive impact climate change will have on all of us?
Answer:
She suggests doing three main things to prepare: adapting to violent storms and floods, preparing for heat and drought, and adapting to the rising seas by rebuilding and restructuring.
The three examples of Arroyo that gives an idea of the massive impact of climate change are adapting to violent storms and floods, preparing for heat and drought, and adapting to the rising seas by rebuilding and restructuring.
What is theory of Arroyo?According to this theory of Arroyo, the first step is to grow food crop varieties that are resistant to drought in order to feed the people that live in these arid areas.
Adopting conservation and protection measures for water sources comes ranked second. Others comprise;
Altruistic water use in residences, farms, and businesses
Utilizing alternative energy sources to cut down on greenhouse gas emissions
Therefore, Arroyo's three adaptation strategies—to ferocious storms and floods, scorching heat, and drought—as well as its rebuilding and reorganizing efforts in response to rising sea levels—all serve as illustrations of the significant effects of climate change.

Photosynthesis and cellular respiration are cellular processes in plants and animals
Which statement correctly compares the reactants and products of the two
processes?
The statement that correctly compares the reactants and products of the two
processes is: the reactants of photosynthesis are the products of cellular respiration and vice versa.
PHOTOSYNTHESIS:
Photosynthesis is the process by which green plants obtain their food (glucose) from the energy they derive from sunlight. The equation of photosynthesis is as follows:6CO2 + 6H2O → C6H12O6 + 6O2
CELLULAR RESPIRATION:
Cellular respiration, on the other hand, is the process whereby living organisms obtain energy (ATP) by breaking down food molecules in their cells. The equation for cellular respiration is as follows:C6H12O6 + 6O2 → 6CO2 + 6H2O
From the description of these two processes, it can be said that carbon dioxide and water (reactants of photosynthesis) are the products of cellular respiration and vice versa.Learn more at: https://brainly.com/question/23126016?referrer=searchResults
A DNA segment has base order TCG TAT AAC. Which copy exhibits an insertion mutation without a frameshift?
A. TCG CCG TAT AAC
B. TCG TAT GAAC
C. TCC TAT AAC
D. TCG TAT AC
A. TCG CCG TAR AAC
Explanation:
I JUST DID THIS QUESTION
The nucleotide sequence TCG CCG TAT AAC exhibits an insertion mutation without a frameshift (Option A).
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an organism.An insertion mutation is a type of mutation where one or more nucleotide bases are added to the original sequence.A frameshift mutation is a type of mutation that alters the open reading frame of the nucleotide sequence, thereby modifying the linear order of amino acids that will be added from the new nucleotide sequence.An insertion mutation of three consecutive nucleotides does not modify the open reading frame of the sequence because they encode for a new codon.In conclusion, the nucleotide sequence TCG CCG TAT AAC exhibits an insertion mutation without a frameshift (Option A).

btw ur intro pls
Feces generally enters into the caecum of the large intestine through the ileocaecal valve
Digestion
Most of the digested foods are absorbed in the small intestines of humans.
Undigested foods, otherwise known as feces are not absorbed but are instead moved into the caecum of the large intestine through a structure known as ileocaecal valve.
The valve prevents the backflow of the feces into the small intestine and the feces are stored in the rectum pending the time they are defecated.

If you were to hike up Mount Kilimanjaro in Tanzania, you would pass through several habitats, including savanna at the base, forest on the slopes, and alpine tundra near the top. Explain how such diverse habitats can be found at one location near the equator.
Given our knowledge of ecosystems, we can confirm that the diverse habitats found at one location near the equator are due to the changes in elevation.
The effects that elevation has on the climate are what enable the diversity of habitats on a single mountain. As elevation increases, atmospheric pressure decreases. This decrease in pressure then causes a decrease in temperature.
The base of the mountain is a dry and hot habitat, while as we travel upwards towards higher elevation we see a transition in habitats into a more tropical forest style and then eventually an alpine tundra, further proving the claim that elevation lowers the temperature.

Name three reasons, as to why, bacteria is so widespread into different life/ecosystems
Answer:
Bacteria are decomposers which break down dead material and recycle it. They also can be producers, making food from sunlight, such as photosynthetic bacteria, or chemicals, such as chemosynthetic bacteria.The most influential bacteria for life on Earth are found in the soil, sediments and seas. Well known functions of these are to provide nutrients like nitrogen and phosphorus to plants as well as producing growth hormones. By decomposing dead organic matter, they contribute to soil structure and the cycles of nature. Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.Explanation:

Compare and contrast light microscopes, scanning electron microscopes, and transmission electron microscopes. Sort each statement into the correct box. some statements may apply to more than one type of microscopes. Some statements may not be used.
Answer: Light microscope:
use a beam of light to produce magnified images
can be used to examine living cells and tissues
Scanning electron microscope:
use a beam of electrons to produce magnified images
can be used to examine DNA
can be used to examine cells
Transmission electron microscope:
use a beam of electrons to produce magnified images
can be used to examine DNA
can be used to examine cells
Explanation: Light microscope: is a commonly used microscope also known as compound microscope. Magnifies images from 40X upto 1000X. It uses ray of visible light to produce a magnified image. The light microscope can be used to view specimen of both living and dead cells or tissues. However, it doesn't give a detailed view of a specimen like electron microscope.
Scanning electron microscope: It uses electron beam as an illuminating source. It has a much higher resolving power than light microscope because it uses electrons instead of light. It magnifies object upto 500000 times the actual size. Internal structures can also be viewed. However, only dead specimen can be used because the beam of electrons can kill the cells. They are of two types:
1. Scanning electron microscope(SEM): an electron beam passes over the specimen's surface and displaces electrons which are then focused on a screen to form an image. Images appear in 3-D
2. Transmission electron microscope: electromagnets magnify the image by passing beam of electrons through a thin specimen. Images appear in 2-D
