Hello! I can't find the constants and am a little confused. Could you help me please??
Answers
Answer:
The constants are just variables that are kept constant throughout the experiment. For example, even though the question did not mention this, we can assume that sunlight is a constant, otherwise it wouldn't be a fair experiment.
Some of the constants could be...
- Sunlight
- Water
- Room temperature
- Hours of light
- Soil quality
Let me know if this helps!

How does the renal portal system differ from the hypothalamo–hypophyseal and digestive portal systems.
Answers
Answer:
The correct answer is - The renal portal system has an artery between the first and second capillary bed. The others have a vein.
Explanation:
A portal system is a system in which is used blood collected from one set of capillaries bed passes through a large vessel or vessels, to another set of capillaries bed before returning to the systemic circulation as the heart can not use these to transfer from all the parts of bodies.
There are several portal systems such as the renal portal system, the hypothalamo–hypophyseal and digestive portal systems, however, The renal portal system has an artery whereas others have a vein.

Group of answer choices genetic differentiation alternative RNA splicing addition of different types of caps and tails to the final version of the mRNA strands retention of different introns in the final version of the different mRNA strands
Answers
Answer:
The correct answer is - alternative RNA splicing.
Explanation:
Alternative splicing, or differential splicing, or alternative RNA splicing, is a controlled process that takes place during gene expression that leads to a single gene to code for multiple polypeptides or proteins.
Alternative splicing produces differential combinations of exons of the same gene that result in gene expression for more than one polypeptide by a single gene.

Amanda does fast once a month, How is the glucose homeostasis in her body maintained while she is
fasting?
A.The blood sugar level decreases while fasting, the alpha cells in Amanda's pancreas releases glucagon into
the blood that stimulates the liver to breakdown glycogen and releases glucose in the blood. In this way, the
blood glucose level rises and maintains homeostasis.
B.The blood sugar level increases while fasting, the beta cells in Amanda's pancreas releases insulin into the
blood that stimulates the liver to take up glucose and convert it into glycogen also the body cells absorb more
glucose. In this way, the blood glucose level declines and maintains homeostasis.
C.The blood sugar level neither increases nor decreases while fasting; the beta cells in Amanda's pancreas
releases glucagon into the blood that stimulates the liver to breakdown glycogen and releases glucose in the
blood. In this way, the blood glucose level rises and maintains homeostasis.
D.The blood sugar level neither increases nor decreases while fasting the beta cells in Amanda's pancreas

In sexual reproduction, what is true about the DNA of the offspring?
A. It is the same as the fathers DNA.
B. It is a different from either parents DNA.
C. It is the same as the mothers DNA.
Answers
Answer:
[tex]\boxed {\boxed {\sf B. \ It \ is \ different \ from \ either \ parent's \ DNA}}[/tex]
Explanation:
Sexual reproduction is one kind of reproduction. It involves two parents to produce offspring. This kind of reproduction occurs when gametes combine. Gametes are sex cells or the egg and sperm. These cells are created in a process known as meiosis. Meiosis is a type of cell division. Cells undergo two divisions and a process known as crossing over. Genetic material is exchanged between two chromosomes, which helps maintain genetic diversity. The 2 divisions result in 4 haploid cells, meaning they have half of the genetic material. After meiosis, there are 4 genetically unique and haploid cells.
When an egg and sperm combine during fertilization, a zygote forms. This is a fertilized egg. It is very unique because each parent contributes half of the genetic material to create a diploid organism with a full set of unique DNA.
You can look similar to your parents and siblings, but (unless you have an identical twin), there is typically some difference because the DNA of offspring is different from either parent's DNA.

What renal and hormonal factors will cause an increased release of aldosterone from adrenal cortex?
Answers
Answer:
Renin; angiotensin I and angiotensin II
Explanation:
Renin is a key hormone involved in the renin-angiotensin-aldosterone system (RAAS), which is responsible for regulating blood pressure in response to changes in blood volume. Renin is secreted primarily by the kidneys to promote the production of the peptide hormone angiotensin in the blood vessels. Subsequently, angiotensin stimulates the release of aldosterone from the adrenal cortex, stimulating sodium retention by the kidneys. Renin acts on its substrate angiotensinogen to yield angiotensin I, which is then converted to angiotensin II by the angiotensin-converting enzyme (ACE). Finally, angiotensin 2 promotes the release of aldosterone by the adrenal cortex, which acts on renal tubules, leading to the reabsorption of sodium and water and the excretion of potassium.
