Answer:
D. steroid
Explanation:
Intracellular receptors are a type of receptors located inside the cell, specifically in the cytoplasm or nucleus. When intracellular receptors are activated by ligands called SIGNALLING MOLECULES, they change shape and regulate genetic expression in the nucleus i.e. they induce turning on and off in a gene.
However, signalling molecules that activate intracellular receptors are usually hydrophobic hormones because they need to easily diffuse through the cell membrane and bind to the receptors located internally. Example of these hydrophobic signal molecules are STEROIDS.
How do scientists think Prokaryotic Cells contributed to changing Earth’s atmosphere to include more oxygen?
Explanation:
Then, about 2.5 billion years ago, oxygen started getting added to the atmosphere by photosynthetic cyanobacteria. “Oxygen is produced as a waste product of photosynthesis. ... “The production and burial of plant matter over long periods causes oxygen levels to rise,” explains Poulsen

A researcher stimulates, with a small electrical charge, a portion of a cat's limbic system. The cat suddenly jumps and acts as if it is fighting. What portion of the limbic system was stimulated
Answer: amygdala
Explanation:
The limbic system, refers to the set of brain structures that's located on the sides of the thalamus. The function of the limbic system include olfaction, behavior, emotion, and long-term memory.
Since the cat suddenly jumps and acts as if it is fighting, the portion of the limbic system that was stimulated is the amygdala.

what are the most common c0vId vaccine myths and how did they start? Explain your answer.
Answer:
The most common myths are:
- C0vid2019 vaccines cause autism
- C0vid2019 vaccines may modify your DNA
- C0vid2019 vaccines are unsafe
Explanation:
The most common myths associated with C0vid2019 vaccines are:
1- C0vid2019 vaccines may cause autism: In 1998, Andrew Wakefield and colleagues published a controversial study in the Lancet where they suggested that the measles, mumps, and rubella (MMR) vaccine may cause autism in some children. However, it has been showed that this study was based on erroneous statements and therefore this publication was retracted.
2- C0vid2019 vaccine may modify your DNA: it has been suggested that vaccines based on viral vectors (e.g. adenoviruses) and mRNA vaccines may modify the DNA of cells. This statement is false because these technologies cannot alter the DNA sequence. These vaccines are based on the production of an mRNA sequence that is translated into a viral protein (spike protein) which triggers an immune response
- C0vid2019 vaccines are unsafe: some people believe that C0vid2019 vaccines are unsafe because they were developed quickly. However, this statement is false because all vaccines (including C0vid2019 vaccines) need to follow rigorous safety standards to be approved by governmental agencies (i.e., they approved all clinical trials).

how can you differentiate between littoral zone and limnetic zone in a pond ecosystem ?
Explanation:
The limnetic zone is the open and well-lit area of a freestanding body of freshwater, such as a lake or pond. Not included in this area is the littoral zone, which is the shallow, near-shore area of the water body.
Explain how the cell division of cancer cells like these are misregulated. Identify genetic and other changes that might have caused these cells to escape normal cell cycle regulation
Answer:
Due to non-functioning of protein.
Explanation:
The cell division of cancer cells like these are misregulated because they can't be control by the proteins that is responsible for the control cell division. The cancer cells can multiply without any growth control factors, or growth-stimulating protein signals that control its growth. There are some proteins that is responsible for control of cell division but due to mutation that protein of substance stop working and the cancer cell grows uncontrollable.
When the particles are equally spaced apart they have reached:
A. Hypertonicity
B. Dynamic Equilibrium
C. Homeostasis
D. Osmolarity
Answer:
B. Dynamic Equilibrium
Explanation:
Since the molecules are still in motion, but an equilibrium has been established, the end result of molecular diffusion is called a "dynamic equilibrium". The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, the movement of molecules does not stop.
Answer:
B. Dynamic Equilibrium
Explanation:
When the particles are equally spaced apart they have reached the dynamic Equilibrium.

Gametes produced by the parents are shown along the __________________ and _______________ sides of the Punnett square.
Answer:
Vertical and horizontal
Explanation:
A punnet square is a tabular chart used in genetics to display the genotypic composition of the offsprings of two parents. To construct a punnet square, the alleles of the gametes produced by the parents is required.
The gametes produced by each parent via meiosis are placed along the vertical and horizontal sides of the punnet square. For example, if a cross occurs between two parents with the following genotype: AaBb and AAbb. The parents will produce the following gametes:
AaBb - AB, Ab, aB, ab
AAbb - Ab, Ab, Ab, Ab
These gametes produces by each parent will be placed along the sides (vertical and horizontal) of a punnet square to determine the genotype of the offsprings that will be produced.

PLEASE ANSWER THE QUESTION BELOW
Answer:
Explanation:
A diagram of a Punnett Square showing the chromosomes involved in the inheritance of sex-linked traits.
The female had the genotype XHXh, and produced the two gametes seen at the left side of the diagram.
The male had the genotype XHY0, and produced the two gametes seen at the right side of the diagram.
The genotypes seen in the center of the square represent the possible genotypes of the F1 generation.
Two female offspring are produced for every two male offspring.
One male and one female offspring inherit normal genes.
One female is heterozygous for the hemophilia trait and is considered a carrier.
One male receives a damaged X-chromosome and inherits the condition known as hemophilia.

Case summary
Diagnosis
Using Anthony's symptoms and initial lab results, describe how you diagnosed that the
problem was kidney failure.
Treatment Goals
Describe the treatment goals for dialysis.
Answer:
Through symptoms.
Explanation:
We diagnosed the problem was a kidney failure due to the decreased urine output , swelling in your legs, ankles or feet, shortness of breath, fatigue, confusion, Nausea and Weakness. The main symptom is the swelling in legs, ankles or feet that tells about kidney failure. The treatment goal of Hemodialysis is to filter waste products and water from your blood. I works just like the kidneys. This treatment is used when the kidney fails to filter waste materials inside the body.
Usually for the initial diagnosis of possible renal failure, there are complaints of pain in the lower back and little urine.
What is dialysis and how does it work?Hemodialysis is the procedure by which a machine filters and cleans blood, doing some of the work that the diseased kidney cannot do. The procedure removes harmful waste from the body, such as excess salt and fluids.
Among the tests that make the diagnosis of acute renal failure are:Measurements of urine outputUrine testsBloodtestsImaging tests, such as ultrasound and CT scanRemoval of a kidney tissue sample for testing (biopsy).With this information, we can conclude that normally for the initial diagnosis of possible renal failure, there are complaints of pain in the lower back and little urine.
