how environmental factors can affect genetics
Answer:
Situational Genetics
Explanation:
The envirnment can control and manipulate species' genes through adaptation. An example of this is horse's teeth building resielnce to grind grass. In order to eat comfortably, horse prefer smushing their food. Over time, they have adapted to the environment by strengthening their teeth.
4. How are histones related to
nucleosomes?
Answer:
Nucleosomes are made up of DNA that's wound around histones
Explanation:
Hope this helps.
Answer:
The nucleosome is the fundamental subunit of chromatin. Each nucleosome is composed of a little less than two turns of DNA wrapped around a set of eight proteins called histones, which are known as a histone octamer. Each histone octamer is composed of two copies each of the histone proteins H2A, H2B, H3, and H4.
what is the difference between biology and technology
Answer:
Biology as a subject studies living beings whereas biotechnology is a related branch of biology which deals with the living organisms to develop various products for human beings. To put it in simpler words, biology focuses on the life forms and life processes within the living organisms.Cryptosporidium parvum (C. parvum) is a single-celled, eukaryotic parasite that infects human cells in the digestive system and causes illness.
a. True
b. False
The statement 'C. parvum is a single-celled, eukaryotic parasite that infects human cells in the digestive system and causes illness' is TRUE. This parasite causes diarrhea.
Cryptosporidium parvum (C. parvum) is a single-cell protozoan that may cause severe self-limited diarrhea in immunocompetent individuals.
Cryptosporidium parvum develops its complete life cycle in the human intestines (also it can be found in animal intestines).
This species (Cryptosporidium parvum) is one of the six (6) known species of Cryptosporidium.

the first group of animals to colonize land was likely
Answer:
horses
Explanation:
When the concentration of ________ in tissue fluid is too high, intracellular water moves into the extracellular fluid compartment.
When the concentration of electrolytes in tissue fluid is too high, intracellular water moves into the extracellular fluid compartment.
OSMOSIS:
Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane. Osmotic principle is based on concentration gradient i.e. difference in concentration across a membrane. Electrolytes represent solute such as salts, ions, sugar etc. Therefore, when the concentration of electrolytes in tissue fluid is too high, intracellular water moves into the extracellular fluid compartment.Learn more at: https://brainly.com/question/2404589?referrer=searchResults

Give an example of display behavior exhibited by a territorial animal.
Answer:
Agonistic (aggressive) displays usually occur near the borders of a territory. When a strange howler monkey approaches the territory of others, resident males set up a tremendous din, warning the intruder off. Many songbirds sit on highly visible perches while singing, providing both auditory and visual displays.

What are the two ways that harmful algal blooms can negatively impact an ecosystem? (Site 1).
Answer:
SEE EXPLANATION FOR ANSWER
Explanation:
Eutrophication: An abundance of cyanobacteria (an algal bloom) is caused by an excess amount of nutrients in the water (phosphorus and/or nitrogen) which depletes the water of oxygen which is vital for plant an animal life. Oxygen is crucial for the survival of an organism, so when there is a lack of oxygen, the results can be fatal. That is why when there are reports of algal blooms, there are almost always mentions of an abundance of dead fish, birds, and other water dwelling organisms (these organisms live in the water, drink from it or use it as breeding grounds etc,) Not only that, but algal blooms produce toxins that can make animals and humans fall ill.
Dead zones: As stated previously, harmful algal blooms deprive the water of oxygen.This can lead to the extreme and create dead zones. Dead zones are zones in an aquatic body where the oxygen levels are not sufficient enough to support aquatic life. Hence why there is no life in dead zones because all of the fish either die, or leave.
Both affect the population of native species and the overall wellbeing of the bodies of water.

What's the only kind of parrot that can't fly?
the condition of having a diploid chromosome complement in which one chromosome lacks its homologous partner.
Monosomy: the condition of having a diploid chromosome complement in which one chromosome lacks its homologous partner.
A trisomy is a chromosomal disorder characterized by an additional chromosome, so the person has 47 instead of 46.
Nullisomic is a genetic condition involving the lack of both the normal chromosomal pairs for a species (2n-2).
So, the correct answer is 'Monosomy'.
