A 67-year-old was previously diagnosed with rheumatic heart disease. Tests now reveal lipoprotein deposition with chronic inflammation that impairs blood flow from the left ventricle into the aorta. Which diagnosis does this history support?

Answers

Answer:

Aortic stenosis

Explanation:

Aortic stenosis is one of the most common cardiovascular diseases. This disease is caused by the narrowing of the aortic valve opening, thereby restricting blood flow from the left ventricle to the aorta. Symptoms of aortic stenosis include, among others,  heart palpitations, swollen feet, chest pain, breathing difficulties, sleeping difficulties, chronic fatigue, etc. Aortic stenosis may be cured by transcatheter aortic valve replacement, which is a minimally invasive surgical technique that allows to replace the narrowed aortic valve.

Plants convert light energy into chemical energy and can be stored in the molecule bonds of organic molecules

Pls mark as brainleist

During the process of photosynthesis plants convert light energy into chemical energy and can be stored in the molecular bonds of organic molecules.

What is photosynthesis?

Photosynthesis is the process in which green plants prepare their own food in the presence of sunlight and light energy is converted into chemical energy by the process of cellular respiration.

The process of photosynthesis takes place in green plants only due to presence of chlorophyll and materials such as sunlight, water, carbon dioxide is required for the process of photosynthesis.

The equation of photosynthesis is represented below:

[tex]6CO2+ 6H2O - C6H12O6 + 6O2[/tex]

The process of food manufacturing in plant is done through photosynthesis and the plants are known as autotrophs as they are the producers.

In the process of photosynthesis the reactant have 6 carbon dioxide molecules and six water molecules, and light energy converted into chemical energy due to presence of chlorophyll.

Therefore,During the process of photosynthesis plants convert light energy into chemical energy and can be stored in the molecular bonds of organic molecules.

Answers

Answer:

B

Explanation:

The Channichthyidae fish, also known as the

crocodile ice fish, lives in the Southern Ocean

around Antarctica. These waters are known to

maintain extremely low temperatures all year,

ranging from approximately 28°F to 35°F. These fish

have adaptations that allow them to live in cold, low

oxygen waters. (a) If you were to examine the

membrane lipid composition of cells from the

Channichthyidae fish identify what you would

expect to find. (b) Justify why you might find what

you identified in part (a).

Answers

A) If you were to examine the membrane lipid composition of cells from the Channichthyidae fish, what you would expect to find is glycoprotein,zona pellucida protein and a less number of haemoglobin that is found in this type of fish.

B) Justification of why you might find what was identified in part (A) is because;

Glycoprotein contains antifreeze compounds,these antifreeze compounds are what provide resistance to freezing of their hypoosmotic tissues by the subzero environment.

If we analyzed the lipid composition of these fish, we could find glycoproteins.

We can arrive at this answer because:

Glycoproteins are formed by a chain of oligosaccharides, linked to a chain of polypeptides, which are side chain lipids.These glycoproteins have different functions in the body.One of the most important functions is keeping the heat.This function allows heat to remain longer in an organism and heat loss to be slower.

In this case, the glycoprotein is an essential molecule in the organism of living beings that live in environments with very low temperatures, such as fish Channichthyidae.

Notice on the graph that the time period between 0 and 3 minutes forms a straight line on the graph.
What does this indicate about the rate of the reaction?

Answers

Answer:

The graph is positive.

Explanation:

Straight line on the graph indicates that the rate of reaction is positive which means that reaction intensity increases with the passage of time. OR in other words, the reaction produces more products with the passage of time and no decrease occurs in their rate because the graph is not coming downward or changing so that's why the graph go in the straight line.

Synthesis of ATP by oxidative phosphorylation is a seriously endergonic reaction. What is the immediate reservoir of stored energy that drives this process?

a. the electron transport chain
b. oxygen
c. proton gradient or energized membrane
d. NADH+ H and FADH2
e. glucose

Answers

Answer:

The correct answer is - option C. proton gradient or energized membrane.

Explanation:

The transport chain reaction or system produces the ATP which is caused by the movement of the proton through the internal membrane from the matrix to intermembrane space by the protein complex.

This makes a concentration gradient of protons that moves through the membrane of mitochondria which is utilized by the enzyme known as ATP synthase to produces ATP molecules by oxidative phosphorylation.

What is DNA?

Deoxyribonucleic acid is a polymer made up of two polynucleotide chains that coil around each other to form a double helix that contains genetic instructions for the development, functioning, growth, and reproduction of all known organisms and viruses. Nucleic acids include DNA and ribonucleic acid.

The fraction of the DNA double helix that supplies structural support to the molecule is known as the phosphate backbone.

The DNA molecule is made up of two strands that wind around each other like a twisted ladder. Each strand has an alternating backbone of sugar (deoxyribose) and phosphate groups.

A nucleotide is made up of a sugar molecule (ribose in RNA or deoxyribose in DNA) linked to a phosphate group and a nitrogen-containing base.

Thus, the correct option is B.

Answers

Answer:

Since they are from different locations, unless we can radiometric Lee date them, we cannot distinguish anything between the two

Explanation:

It is not possible to determine information about the geological layers of different locations just by viewing the images, as the question above asks. This is because these two sites have different natural elements that acted on these layers and these fossils differently. In this case, making conclusions only with the visualization of the images, would not promote accurate and correct information. Ideally, a radiometric dating would be performed in both cases, so that accurate conclusions could be created.

How can the role of epigenetics in cancer be reconciled with the idea that cancer is caused by the accumulation of genetic mutations in tumor-suppressor genes and proto-oncogenes

Answers

Answer:

Epigenetic mechanisms control the activity of genes involved in DNA repair pathways and cell growth

Explanation:

Epigenetics can be defined as the study of the alterations in gene expression patterns that do not involve alterations in the DNA sequence. Epigenetic mechanisms include 1-DNA methylation, 2-histone modifications (i.e., methylation, acetylation, phosphorylation, ubiquitination, etc.) and 3-non-coding RNA pathways (microRNAs, long ncRNAs, etc). These epigenetic mechanisms work together to control gene expression patterns by activating or silencing genes at the level of transcription, in a mode that is dependent on the cell type and developmental stage. In consequence, the failure of the epigenetic mechanisms modifies the activity of genes which may be involved in DNA repair pathways and thereby it may lead to severe disorders including some cancers.
