The correct answer is D. taking in wastes from other cells.
Explanation:
The correct answer is D. taking in wastes from other cells.
Homeostasis is the process by which cells, organisms, or systems maintain stable internal conditions. To achieve and maintain homeostasis, cells perform various processes such as making new molecules for growth, transporting substances across cell membranes, and breaking down unneeded molecules. However, taking in wastes from other cells does not contribute to maintaining homeostasis and is not a recognized process for this purpose.

Cell membranes have each of the following functions except for giving the cell a rigid, inflexible shape. Thus, the correct option for this question is A.
What is a Cell membrane?
A cell membrane may be defined as a type of biological membrane which separates the inner surroundings of the cell with respect to the outer environment. It is semi-permeable in nature. It performs numerous functions for increasing the survival of an organism.
Cell membranes generally protect the inner content of the cell along with various organelles from the outer environment. It also regulates the movement of materials in and out of the cell either by simple diffusion or by transporters. It allows the easy passage of water into the cell.
Therefore, cell membranes have each of the following functions except for giving the cell a rigid, inflexible shape. Thus, the correct option for this question is A.

the best announcement about the data collected on Amir’s desk could be Wave three resulted from positive interference, and Wave 4 resulted from adverse interference.
what's constructive & detrimental interference?
constructive interference takes place wherein the traces (representing peaks), move over each other. In different words, whilst waves are in segments, they intrude constructively. unfavorable interference occurs whilst waves are completely out of segment a top lies on the midpoint of two waves.
Why is it known as adverse interference?
In reality, at all factors, the 2 waves exactly cancel each other out and there is no wave left! this is the unmarried maximum extraordinary component of waves. The sum of waves can be less than either wave, by myself, and might even be zero. that is referred to as damaging interference.

Answer:
The result of the translation of the mRNA sequence AUG CAC UCG into protein is methionine, histidine and serine.
Explanation:
Messenger RNA (mRNA) is responsible for carrying the sequence of nitrogenous bases of its molecule to the ribosome to be translated into amino acids and synthesize proteins.
Three nucleotides of mRNA form triplets or codons that can encode:
- The initiation of protein synthesis, with the AUG codon also coding for methionine.
- Amino acids to be added to the peptide chain.
- Stopping protein synthesis.
For the mRNA base sequence AUG CAC UCG, the amino acid sequence that corresponds to the synthesized peptide or protein is Met-His-Ser, i.e. methionine, histidine and serine.

Answer:
The options are
a. A lack of estradiol.
b. Moderate levels of estradiol during an early stage of development.
c. A high level of testosterone during an early stage of development.
d. A high level of testosterone during the late part of puberty.
The answer is b. Moderate levels of estradiol during an early stage of development.
Testosterone is a hormone which is responsible for the secondary sexual characteristics of a male while estradiol is the hormone responsible for the secondary sexual characteristics of a female.
This is why estradiol is the hormone responsible in female development regardless of the chromosomes

Answer:
Medulla oblongata. (Ans. A)
Explanation:
Medulla oblongata is present in the brain, in front of the cerebellum. It controls the number of functions in the body. It helps to transfer messages to the thalamus & spinal cord, from the body.
Medulla oblongata helps to regulate breathing, blood pressure, heart rate, sneezing, and digestive activities. Medulla oblongata part of the brain is a center for respiration & circulation. Sensory & nerve cells from the midbrain & forebrain travel through the medulla. It receives its blood supply from many arteries (including anterior spinal, posterior inferior cerebellar and the vertebral artery's)
Final answer:
The medulla oblongata in the brain controls crucial autonomic functions like breathing, blood pressure, heart rate, and digestion.
Explanation:
The major centers concerned with autonomic control of breathing, blood pressure, heart rate, and digestive activities are located in the medulla oblongata (option A). The medulla oblongata is an important part of our brainstem, located just above the spinal cord. It is crucial as it controls various autonomic functions such as breathing, heart rate, blood pressure, and digestion.
