What is the phenotype ratio for this cross?
Answer:,,
Explanation:
Answer:
3 long and 1 short
Explanation:
3 of the squares have the dominant allele for long needles (L) therefore all 3 would all have long needles because in order for a cactus plant to have short needles it would have to have only the short allele (l) like the one on the bottom right corner

Research and find a zoonotic disease that you find interesting. Write a news report that could be used as a script for a TV news show.
Instructions
Include the following in your report:
Explain what a zoonotic disease is.
Describe the disease.
Explain how to protect yourself from becoming infected.
Your report should be 100 to 125 words long.
I need a little help i will mark you branleist
Zoonotic diseases are animal diseases that can be transmitted to humans. Transmission can be by ingestion, inhalation, bites, scratches, contact with contaminated products, and vector-borne. There are over 200 zoonotic diseases that can possibly threaten your health and involve several different causative agents, such as bacteria, parasites, viruses, and others. I am only going to inform you of just a hand full that is caused by bacteria and contaminates cattle. Once the cattle on large commercial farms become infected it can be a challenge to get rid of and contain.
Wash hands before and after animal handling.
1. Do not eat or drink in the animal housing areas.
2. Wear coveralls, farm specific clothing or laboratory coats when handling animals.
3. Avoid handling sick animals or animals with lesions unless gloved.
4. Wear a mask if you are allergic to animal hair or dander or if feed or bedding dust is present.
5. If you are sick, DO NOT enter the agricultural animal facilities. You are more susceptible to other infective agents and you may transfer pathogens to the animals!
6. Routinely wear gloves when cleaning animal area.
7. Note progression of any illness. Report illnesses to your supervisor.
8. Inform physician of your animal related activities.

containing 1 mg/mL of sugar; the second is given water containing 2 mg/mL
of sugar; and the third is given water containing 3 mg/mL of sugar. After four
weeks, the average length of the flies in each group is determined.

I WILL GIVE YOU BRAINLIEST
Answer:
1) As soon as the paper cuts into the cells of your skin, your body springs into action. First, blood cells called platelets join together at the paper cut and form a clot to stop the bleeding.
The process is called Blood clotting.
2) The cell that are made will have the same same amount of DNA/chromosomes.
3) Chromosomes come in pairs. Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father. Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born.

B)adenine binds with cytosine
C)cytosine binds with thymine
D)cytosine binds with guanine
E)adenine binds with guanine
F}thymine binds with guanine
Answer:
A,D
Explanation:
The results from Chargaff's experiment includes adenine binding with
thymine and cytosine binding with guanine.
Chargaff was a Scientist who performed various experiment using the DNA.
He discovered that DNA varied and had purine and pyrimidine bases.
He also discovered that the amount of cytosine should be equal to the
amount of guanine and that the amount of adenine must be equal to the
number of thymine and that both should be paired together.

List the sequence of events that occur as the avocado seed germinates.
Answer: The sequence of events of avocado seed germination includes:
Water absorption --> enzyme activation --> radicle emerges --> lengthening of the hypocotyl --> growth of epicotyl and plumule development --> shrinking of the cotyledons.
Explanation:
Germination is defined as all the changes that occurs when a seed embryo resumes it's growth and development to become an independent seedling. Seeds usually germinate in two ways:
--> EPIGEAL germination: in this type of germination, the hypocotyl grows rapidly and elongates, carrying the cotyledon above the soil.The AVOCADO seed is a typical example of a dicotyledonous plant.
The sequence of events of avocado seed germination starts by imbibition which is the rapid in take or absorption of water by the seed through osmosis. Hydration of the embryo activates the enzymes in it which converts insoluble stored food materials into soluble forms. The testa splits and the radicle emerges first. It grows downwards as the primary root from which root hairs and branch roots arise( to form a tap root system). Next, the hypocotyl lengthens, pushes its way up through the soil carrying with it the cotyledons and the plumule. The cotyledons turn green on exposure to sunlight and start to photosynthesize. The epicotyl then grows and the plumule develops into a green shoot. By the time the first foliage leaves grow and begin to photosynthesize, the cotyledons shrink and drop off.

Even though mutations are relatively rare, they are still a concern in bacteria populations. Why?
Answer:
Mutations can provide resistance to antibiotics If we were to treat the bacterial population with that specific antibiotic, only the resistant bacteria will be able to multiply; the antibiotic selects for them. These bacteria can now increase in numbers and the end result is a population of mainly resistant bacteria.
Explanation:
Even though mutation is rare in bacteria, it is still important to be concerned about bacteria. The reason is that if any mutation happens that converts the bacteria into antibiotic-resistant bacteria, then this would be harmful.
What is mutation?Mutation is a phenomenon in which a change is seen in an organism's genome. It may be induced by chemical factors, environmental factors, etc. The mutation may be positive or negative.
In a population, evolution is seen due to mutation. It is one of the factors behind evolution. In bacteria, the mutation happens too. If any sort of mutation happens that makes them antibiotic-resistant, then it would be harmful for humans. Humans take antibiotics that destroy harmful bacteria. If these bacteria mutate their genetic constitution and become resistant, a higher dose of antibiotic will be required next time to destroy such harmful bacteria.
Hence, mutations in bacteria are harmful even though they are rare.

Which approach would be least helpful in determining genetic differences between species?
Answer:
the least helpful would be a straight up guess, the best way would be to to back in the history of that species and study how they lived and survived and reproduced and all that stuff
Explanation:
Comparing physical characteristics between species is not a reliable method for determining genetic differences because many physical traits are influenced by environmental factors and may not necessarily reflect the underlying genetic differences between species.
What is an example of this ?For example, two species may have different fur colors or patterns, but this difference may be due to environmental factors such as exposure to different types of light rather than genetic differences.
In contrast, analyzing DNA sequences can provide a more precise and objective way to identify genetic differences between species. By comparing the DNA sequences of different species, scientists can identify variations in genes and regulatory regions that may be responsible for differences in traits or behaviors between species.
This approach can also reveal the evolutionary relationships between species and provide insights into how genetic variation has driven the diversification of life on Earth.
Therefore, Advances in genomic technologies have made it increasingly feasible to sequence and compare the genomes of diverse species. Comparative genomics has already revealed many insights into the genetic basis of traits such as human disease susceptibility, adaptation to environmental challenges, and the evolution of complex traits such as intelligence and social behavior.
