Answers

Answer 1

Answer:

Cell is made of molecules whereas atoms make up molecules. Cells are the smallest functioning unit in a living organism.

Which of the following events contributes to the termination of a signal generated by the binding of a ligand to a receptor tyrosine kinase? Only one answer is correct
1. Phosphatases hydrolyze key phosphorylated residues.
2. Kinases hydrolyze key phosphorylated residues.
3. Kinases phosphorylate key residues.
4. The receptor tyrosine kinase dimerizes.
5. GTPase removes a phosphoryl group from GTP.
6. Phosphatases phosphorylate key residues.

Answers

Answer:

1. Phosphatases hydrolyze key phosphorylated residues.

Explanation:

Receptor Tyrosine Kinases (RTKs) are high-affinity transmembrane protein receptors that bind to a wide variety of ligands (e.g., growth factors, cytokines, hormones). These receptors (RTKs) have a transmembrane domain and therefore these proteins act as membrane receptors, as well as exhibit catalytic activity. The intracellular C terminal region of RTKs contains catalytic domains responsible for both autophosphorylation and tyrosine phosphorylation of their protein substrates. Moreover, Protein Tyrosine Phosphatase (PTPs) are critical enzymes that remove phosphate groups from tyrosine residues in different substrates (including RTKs), thereby regulating key signaling pathways such as cell proliferation, cell differentiation, and cell-cell adhesion.

3. A bacterial isolate from a urine specimen was grown in culture, Gram stained, and then tested for its ability to ferment sugars and hydrolyze various subtrates. What approach to bacterial identification is this an example of

Answers

Answer:

Phenotypic approach for bacterial identification

Explanation:

Bacterial identification can be done by conventional methods, which are based on phenotypical characteristics. These methods are much affordable and reasonable.

Phenotypical identification is based on bacteria´s observable characteristics, such as their morphology, development, and biochemical/metabolic properties.

It is important to consider that these methods do not provide absolute certainty. They can only indicate the genera or species to which the bacteria under study may belong.

Some primary evidence is usually used for fast bacteria identification:

Gram staining, morphology, growth at different media or different incubation atmospheres, glucose fermentation, spores production, motion, aerobiosis/anaerobiosis, among others.  

Knowing that the bacteria in the exposed example was isolated and grown in culture, then Gram-stained and tested for biochemical reaction, we can assume that the approach for its identification is phenotypic.  

How do sinkholes form? Be sure to provide a detailed explanation of sinkhole formation.

Answers

Answer:

See below

Explanation:

Over hundreds of thousands of years, layers of rocks like bedrock and limestone erode. Then, a hole or cavity forms when it erodes. Slowly, the matter above the cavity falls in. This causes it to expand. Drought is also another reason that sinkholes form in the ground.

Answer:

Sample Answer edge 2021

Explanation:

When it rains, rainwater, which is slightly acidic, soaks into the ground and becomes more acidic as it moves through the soil. When this water comes in contact with the bedrock, it reacts with the limestone, dissolving it. As the water flows through the ground, it carries the dissolved limestone away with it, enlarging the natural holes and cracks that were already present in the rock. Over time, large cavities may form in the bedrock. Sinkholes often form when the overlying sediments become too heavy for the ceiling of an underground cavity to support. The ceiling gives way and the overlying sediments collapse into the cavity.

The most common Class II variant is the F508del variant, which is missing the 508th amino acid in the protein but has an otherwise normal sequence. Loss of this amino acid leads to misfolding of the protein, and the misfolded protein is not properly transported to the membrane. Based on this information, how many nucleotides are deleted in the CFTR allele encoding this variant?

Answers

Answer:

The correct answer is - 3 (two codons of 507th that are U, C, and the first nucleotide of 508th codon U).

Explanation:

Each amino acid is coded by a three-nucleotide base long codon. So in the case of the F508del variant, there is a deletion of three nucleotides that is encoded for phenylalanine amino acid.

In this isoleucine is encoded by 507th codon that is AUG and 508th codon is UUU codes for Isoleucine.

In this case, two codons of 507th are U, C, and the first nucleotide of 508th codon U. So overall three nucleotides are deleted in the F508del variant..

What must happen before meiosis can begin ?

prior to undergoing meiosis, a cell goes through an interphase period in which it grows, replicates its chromosomes, and checks all of its systems to ensure that it is ready to divide. Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase.

What is rcbL, and why is it a particularly useful molecule for studying evolutionary relationships in plants and green algae

Answers

Answer:

RBCL denotes for 'rubisco protein.' It is characterized as 'a plant enzyme which catalyzes both the fixing of carbon dioxide found in atmosphere during photosynthesis and the reverse process of photorespiration.' It plays a very significant role in studying, as well as, in evaluating relations associated with phylogenetics in plants primarily along with green algae as it assists them to produce energy molecules by using carbon dioxide from the atmosphere. It has therefore been the key factor behind a number of organic carbon that is discovered in our surrounding biosphere.

What is the phase that not all cells enter, but it is a phase where cells are not actively dividing

Answers

Answer:

The phase that not all cells enter, but is a phase where cells are not actively dividing is called the G0 or non-dividing phase.

Answer:

G₀ phase

Explanation:

Some types of cells divided slowly or not at all. These cells may exit the G₁ phase and enter a resting phase called G₀ phase. In G₀ phase, a cell is not actively preparing to divide. It's simply doing its job. For some cells, G₀ is a permanent state, while others may restart cell division given the right signals.

Answers

Answer:

She is at risk for future obesity

Explanation:

The correct conclusion could be drawn is she is at risk for future obesity. BMI is a body mass index that is derived from the mass and height of the person.

How BMI is calculated?

The formula is BMI = kg/m2

Where kg is a person’s weight in kilograms and m² their height in meters squared.

BMI categoriesUnderweight = <18.5Normal weight = 18.5–24.9Overweight = 25–29.9Obesity = BMI of 30 or greater

Thus, it is concluded that Ariella is at a risk for future obesity according to her BMI percentile.
