Which of the following is least true of or related to an endocrine gland?

Biology
1 answer:
dolphi86 [110]3 years ago
8 0

Answer:

The statement that is least true of an endocrine gland is d. all hormones are steroids.

Explanation:

The endocrine glands are a set of glands that are devoid of excretory ducts (they are ductless glands), produce and release hormones (messenger substances) directly into the bloodstream. The hormones can be steriodeas, produced by endocrine cells from cholesterol and non-steroids, synthesized from amino acids (Proteins, peptides, glycoproteins, derived from simple amino acids)

DNA samples should be stored in an airtight containers to prevent contamination true or false
Aleksandr-060686 [28]

Answer: True

Explanation:

DNA is a biological evidence. It is a heredity material which is present in all organisms on earth. The DNA in humans can be taken as sample from nails, bones, blood, skin, hair and other sources.

The DNA samples can be taken so as to establish the identity of the culprit, victim or any one which is associated with crime.

The DNA evidence has applicability as a potent evidence in the court of law. Thus utmost care should be taken to preserve it's integrity until it is analysed and presented in the court of law.

Thus the DNA evidence should be collected and preserved in airtight containers so as to prevent the entry of airborne pathogens like bacteria, virus these can contaminate the sample evidence and can make the evidence not of any use.

What is the sequence of the mrna made from the gene aaacaggtccca?
olga nikolaevna [1]
<span>The mRNA is made by using the gene AAACAGGTCCCA as a template for complementary base-pairing. The pairings are: G (Guanine) to C (Cytosine), C to G, T (Thymine) to A (Adenine), and A to U (Uracil, as Tyhmine doesn't occur in the RNA). The resulting mRNA is UUUGUCCAGGGU.</span>

When a singly ionized potassium ion moves through a channel in the membrane passing from the outside to the inside, what is the
Korolek [52]

The magnitude of the work done by the electric field of the membrane is <u>W = 1.28 × 10⁻²⁰ Joules</u>.

We start with the necessity to take into account a value for the voltage present there in order to solve this problem by first considering that the membranes have two layers, one internal and one external, each responsible for producing a potential difference between the two levels.

As a result, in order to find a solution, it is necessary to take into account the potential difference between the two surfaces. In this instance, we'll assume a particular value for the load, but the recipient is free to substitute a different value if they prefer.

The product of the potential difference and the charge is used to define the work that an electric field performs. The charge of the potassium ion will be equal to that of its electron, so,

q = 1.6 × 10⁻¹⁹ Coulombs

Then the Work would be:

W = Vq

Here,

v = Potential difference

q = Charge

The 80mV potential difference we will have is quantified as follows:

W = (80mV (1V/1000mV))( 1.6 × 10⁻¹⁹ C)

W = 1.28 × 10⁻²⁰ Joules is the amount of work that the membrane's electric field has produced.

Experiments on the positive phototropic response of plants indicate that ______. A. light destroys auxin B. auxin moves down the
artcher [175]

The answer is auxin can move to the shady side of the stem.

Phototropism is a reaction to environmental factors. It is a plant's response to sunlight in the form of movement. In plants, phototropism is very prevalent. In actuality, it is necessary for plant growth. Other plant movements also occur in response to touch, water, gravity, and other factors. Phototropism was discovered due to well-known experiments by Charles Darwin and Boysen Jensen.

There are two types of phototropism:

  • Positive phototropism
  • Negative phototropism.
