Bernice is interested in studying metabolism, specifically how the energy needs of the human body change through the life span. Option A is correct.

Metabolism refers to the chemical processes that occur in the body to maintain life. One important aspect of metabolism is the conversion of food into energy, which is needed for all bodily functions. The energy needs of the human body vary throughout the life span, depending on factors such as age, sex, body size, physical activity level, and health status.

For example, infants and children have higher energy needs per unit of body weight than adults due to the rapid growth and development that occurs during these stages. Similarly, pregnant and lactating women have increased energy needs to support the growth and development of the fetus and to produce milk for the infant.

Understanding how the energy needs of the human body change through the life span is important for maintaining good health and preventing chronic diseases such as obesity and diabetes. Hence Option A is correct.

The given sequence mutation represents the template and non-template strands of DNA. The template strand is the one that is used as a template during transcription to produce RNA. The non-template or coding strand is the complementary sequence to the template strand.

To determine the amino acid changes caused by the mutation, we need to analyze the sequence changes. Let's break it down step-by-step:

1. The template strand:
  3' - gtt - tac - ctt - ctc - ttc - tca - gac - atc - gca - 5'
2. The non-template or coding strand:
  5' - caa - atg - gaa -gag - aag -agt - ctg - tag - cgt - 3'

Now, let's compare the original codons on the non-template strand with the corresponding codons on the template strand.
1. The original codon:
  caa (coding strand) -> gtt (template strand)
  This corresponds to the amino acid glutamine.
2. The original codon:
  atg (coding strand) -> tac (template strand)
  This corresponds to the amino acid methionine.
3. The original codon:
  gaa (coding strand) -> ctt (template strand)
  This corresponds to the amino acid leucine.
Therefore, the mutation causes amino acid changes from:
1. Glutamine
2. Methionine
3. Leucine

It is important to note that the specific mutation is not provided in the given sequence, so we cannot determine the exact nature of the mutation or its impact on protein function. However, based on the changes in the amino acid sequence, we can infer that the mutation leads to alterations in the protein structure and potentially its function.

Yogurt is typically diluted with water before being used as a sample for microscopic examination. It is simpler to examine the bacteria and other yogurt ingredients under a microscope thanks to the water's assistance in separating and dispersing them. Yet occasionally, different liquids, including saline solution or buffer solutions, can also be utilized for this.

Locate a region of the yogurt that is relatively thin under low power; this is where the bacteria are. For a better look of the bacteria, change the magnification to high power (400X for most microscopes). These tiny organisms will be significantly easier to see if your microscope has an oil immersion lens.

By homogenizing and dissolving curds under alkaline conditions, as well as by subjecting them to lysis with proteases or surfactants, it is possible to separate LAB from yogurt (Gunasekera et al., 2002). Centrifugation is used to gather the cells following these procedures.

A biome is a sizable region distinguished by its flora, fauna, soil, and climate.

Thus, Aquatic, grassland, forest, desert, and tundra biomes are the five main types, while some of these can be further broken down into more specialized groups, such as freshwater, marine, savanna, tropical rainforest, temperate rainforest, and taiga and climate.

Freshwater and marine biomes are both included in aquatic biomes. Bodies of water with a salt concentration of less than 1% are referred to as freshwater biomes and include ponds, rivers, and lakes.

Nearly 75 percent of the surface of the Earth is covered by marine biomes. The ocean, coral reefs, and estuaries are all examples of marine biomes.

Thus, A biome is a sizable region distinguished by its flora, fauna, soil, and climate.

Explanation:

Feeding is regulated during the short-term through the release of intestinal peptides, insulin, and activation of sensory and hypothalamic neurons the complex interaction between hormones and the nervous system helps maintain energy balance and prevent overeating.

Intestinal peptides like cholecystokinin (CCK), peptide YY (PYY), and glucagon-like peptide-1 (GLP-1) play vital roles in appetite regulation. When food enters the gastrointestinal tract, these peptides are released, signaling the brain to induce satiety and reduce food intake. Insulin is another hormone that contributes to short-term feeding regulation, secreted by the pancreas, insulin's primary function is to regulate glucose metabolism. High levels of insulin indicate the presence of nutrients in the bloodstream, which helps regulate food intake by signaling the brain that the body has sufficient energy, reducing hunger.

Sensory neurons in the gastrointestinal tract detect the presence of food and send signals to the hypothalamus, a brain region responsible for maintaining energy homeostasis. The hypothalamic neurons, specifically in the arcuate nucleus (ARC), respond to these signals by producing appetite-stimulating (orexigenic) or appetite-suppressing (anorexigenic) neuropeptides, these peptides interact with other brain regions to control feeding behavior. In summary, short-term regulation of feeding involves the release of intestinal peptides, insulin, and activation of sensory and hypothalamic neurons. This complex interaction between hormones and the nervous system helps maintain energy balance and prevent overeating.

In 1855, noted physician Rudolph Virchow concluded that cells come from preexisting cells, and the one that is true is that chromosomes are copied during mitosis, which is option D.

Rudolph Virchow's conclusion that cells come from preexisting cells supports the third component of the cell theory. Before Virchow's work, it was commonly believed that cells could arise spontaneously from non-living matter. However, Virchow's observations and experiments provided strong evidence that cells could only arise from preexisting cells. In the mid-1800s, Virchow studied cell division and observed that cells divide to form new cells. He proposed that cells could only come from other cells and that this process of cell division was responsible for the growth, development, and repair of living organisms.

Hence, the one that is true is that chromosomes are copied during mitosis, which is option D.

Answer:

1. RNA 2. Insulin 3. Lysine 4. Lactose 5. Fat

Explanation:

RNA contains both nitrogen and phosphate hence it is the substance in tube 1.

Insulin being a protein contains sulfur hence it is the substance in tube 2.

Lysine does not hydrolyse hence it is the substance in tube 3.

Fat is hydrophobic hence it is the substance in tube 5.

Since lactose does hydrolyse and because the rest have been identified, it must be the substance in tube 4.

Based on these data, each tube is identified as:

Hydrolysis doesn't occur in lysine so, the 3rd tube contains lysine.

Nitrogen is present in Insulin(in amino acids), RNA(in nucleotides), and Lysine. Insulin consists of two polypeptide chains (A and B) which are joined by sulfur bonds. So, 2nd tube contains insulin.

In RNA, nucleotides are present which consists of phosphate groups. Adjacent nucleotides are joined together by phosphodiester bonds. So, 1st tube contains RNA

Fatty acids are Hydrophobic due to the presence of long hydrocarbon chains. So, 5th tube contains Fat.
