Which molecule, chlorophyll a or chlorophyll b, is more polar?.
Answer:
Molecular Structure and Polarity. The distinctions between the chlorophylls, which are more polar than β-carotene are slight: chlorophyll a has a methyl group (Y=CH3) in a position where chlorophyll b has an aldehyde (Y=CHO). This makes chlorophyll B slightly more polar than chlorophyll A.

Inadequate blood flow to the heart muscle can cause an area of damaged cardiac tissue known as a(n) .
A myocardial infarction comprises a series of changes in the cardiac tissue that originate when there is an inadequate blood flow to the heart muscle or a coronary artery becomes blocked.
What is a myocardial infarction?It is characterized by the sudden appearance of a picture of ischemic suffering (lack of irrigation) to a part of the heart muscle produced by the acute and total obstruction of one of the coronary arteries.
It is recognized by the sudden appearance of the characteristic symptoms of intense pain in the chest, in the precordial area and a feeling of general malaise.
Therefore, we can conclude that a myocardial infarction comprises a series of changes in the cardiac tissue that originate when there is an inadequate blood flow to the heart muscle.

The processes of transcription and translation are critical pieces of gene expression to produce proteins in all living cells on earth.
Which statements correctly differentiate transcription and translation? More than one statement may apply.
Transcription is the process of synthesizing RNA from DNA, while translation is the process of synthesizing proteins from RNA.
Transcription involves the production of a complementary RNA copy of a DNA sequence, using RNA polymerase and nucleotides. The resulting RNA molecule, called messenger RNA (mRNA), carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm.
Translation, on the other hand, involves the reading of the mRNA sequence by ribosomes, which assemble amino acids into a polypeptide chain according to the genetic code. This process involves transfer RNAs (tRNAs) that carry specific amino acids and match them to the codons on the mRNA. Together, transcription and translation enable the transfer of genetic information from DNA to proteins, which perform vital functions in cells.

A cell has 6 chromosomes during G1. During G2 it has
How many chromatids and
strands of DNA?
Answer:Neuronal cells in G2 phase demonstrate tetraploid (4N) DNA content or, more precisely, possess a nucleus with 46 replicated chromosomes.
Explanation:In the G1 phase, there are 12 chromosomes. In the S-phase of the cell cycle, the amount of DNA gets doubled. There is doubling of the chromatids but the chromosomes number remains same. The number of chromosomes in the G2 phase will be same as 12 chromosomes and the number of chromatids will be 24.
Neurons in the visual cortex respond to which type of stimulus?
Answer:
luminance
Neurons in the visual cortex respond essentially to the variations in luminance occurring within their receptive fields, where each neuron fires maximally by acting as a filter for stimulus features such as orientation, motion, direction and velocity, with an appropriate combination of these properties
Explanation:
Neurons in the visual cortex respond to luminance stimulus. They respond selectively to various stimuli depending on the features.
What do you mean by Neurons?Neurons may be defined as the cells which are responsible for receiving sensory input from the external world and processed in the brain.
Neurons in the primary visual cortex respond to local edges or contours at a particular orientation, motion, direction, and stereoscopic depth.
Therefore, neurons in the visual cortex respond to luminance stimulus.

Adipose tissue is one of the most hydrated of all tissues in the human body
Answer:
False
Explanation:
Adipose tissue is one of the lease hydratetd of all tissues in the human body.
Adipose tissue is one of the most hydrated of all tissues in the human body and is one of the maximum hydrated of all tissues withinside the human frame.
What is intracellular fluid?The maximum ample cation in intracellular fluid is sodium. Solutes, irrespective of size, are capable of pass freely among booths due to the fact water includes them alongside the osmotic gradients.
Adipose tissue carries approximately 10% of water, even as muscle groups carries approximately 75%. In Netter's Atlas of Human Physiology, frame water is damaged down into the subsequent booths: Intracellular fluid (2/three of frame water) is fluid contained inside cells.

Define Photosynthesis.
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
