Answers

Answer 1

cardiorespiratory fitness is important because allows the blood to carry oxygen and nutrients to the body.

The intensity of your workout and oxygen use are measured using metabolic equivalents (METs). They gauge energy use when at rest.

Maximum oxygen uptake (VO2 max) and how it is utilised during vigorous exercise are the two factors used to gauge cardiorespiratory endurance. Increased oxygen uptake indicates that your cardiorespiratory system is operating effectively and that you are using more oxygen. VO2 tests are often performed in a lab, hospital, or clinic with the assistance of a clinician or exercise physiologist. With a certified fitness teacher, you can perform submaximal testing.

Your cardiorespiratory endurance is assessed using submaximal exercise tests. Your cardiorespiratory endurance may be enhanced with the help of these exercises. They can be performed anytime, anywhere, and don't require a lot of equipment.

if i gave you a protein you knew nothing about (not a fluorescent protein) and asked you to predict its function, which do you think would be most helpful to analyze, primary, secondary or tertiary structure?

Answers

The amino acid sequence of a protein determines how it will behave biologically, and alterations to the amino acid sequence will affect the protein's 3D structure.

If you're given a protein X whose function is unknown, you can use NMR or X-Ray crystallography to find out its structural information, or you can use computational methods like threading for 3D structure prediction, PSIPRED, the Chou-Fasman Method, or homology modelling (based on finding homologues of the given protein's structure in the PDB and modelling it using a tool like Swiss Modeller). discover physiochemical characteristics such as molecular weight, amino acid composition, PI, etc.,

So briefly, use CD spectroscopy, Edman degradation, NMR, and mass spectrometry to find primary sequences for unknown proteins. Every one of these is for experimental purposes.

Using the image below, identify the type of membrane transport shown (DIFFUSION, FACILITATED DIFFUSION, ACTIVE TRANSPORT) and explain how it works.

Answers

Answer:

Diffusion

Explanation:

Diffusion and Facilitated diffusion are the only two passive transports present. The other would be the active transport.

The differences between diffusion and facilitated diffusion is that diffusion is the substance passing through a phospholipids (lipid bilayer), while facilitated diffusion uses proteins in the bilayer that will allow this substance to pass through.

Like in the diagram shown, we start off with a high concentration on the top of the lipid bilayer, but we want to have both sides equal. That's why diffusion happens where at the end both concentrations on each side are equal.

3. Cells copy once and divide twice making 4 cells
4. Cells copy once and divide once making 2 cells

Answers

Mitosis is the equational division, in which one parent cell divides to form two exact copies of daughter cells which are identical to the parent cell. Thus, the correct option is 4.

What is Mitosis?

Mitosis is a type of cell division which occurs in all types of cells. This is also known as equational division because the number of chromosomes remains constant after the division. In this division, one parent cell undergoes division to form two daughter cells which are clones of the parent cell.

In this division, a single DNA splits into two daughter cell's DNA. The mitotic division consist of karyokinesis and cytokinesis. Karyokinesis is the division of nucleus which includes different phases such as Prophase, Metaphase, Anaphase, and Telophase followed by the division of cytoplasm (cytokinesis).

superfractor va, an engineered factor v molecule, effectively reduces bleeding and acute coagulopathy in mouse models of trauma and shock. the american society of hematology

Answers

Here, we looked into the potential for reducing traumatic bleeding and preventing or normalizing hemostasis parameters suggestive of acute traumatic coagulopathy (ATC), a process thought to be distinct from disseminated intravascular coagulation, through targeted intervention with an engineered factor FV variant (superFVa), resistant to inactivation by APC (DIC).

Traumatic bleeding is a leading cause of death and disability in the absence of particular treatments. A high mortality risk condition known as acute traumatic coagulopathy (ATC) is seen in 30 to 50 percent of individuals who also have bleeding. Activated protein C (APC), whose excessive production promotes the quick depletion of engineered factor FV variant and FVIII and hyperfibrinolysis, may play a part in the onset of ATC, according to recent studies.

Only mice who underwent both trauma and shock in the trauma/shock model acquired ATC, as shown by a large APTT extension (25.4 to 36.1 seconds), which was accompanied by a severe drop in engineered factor FV variant and FVIII, a minor reduction in fibrinogen, and no effect on FX or FII.

A plant can store starch in many areas, from the leaves down to the roots .What does this tell us about the transport of sugar solution in phloem tubes?

Answers

A high concentration of sugar at the source creates a low solute potential (Ψs), which draws water into the phloem from the adjacent xylem. This creates a high pressure potential (Ψp), or high turgor pressure, in the phloem. The high turgor pressure drives movement of phloem sap by “bulk flow” from source to sink, where the sugars are rapidly removed from the phloem at the sink. Removal of the sugar increases the Ψs, which causes water to leave the phloem and return to the xylem, decreasing Ψp.

Answers

The genotypes of the parents if you assume that mendel conducted a cross and the following progeny were produced: 202 gray and 198 white is GG and Gg.

Gregor Mendel uncovered the basic principles of heredity through his study on pea plants. He concluded that genes are inherited from each parent as separate, paired units. Mendel observed how parental genes separated and if they showed up as dominant or recessive qualities in the children.

Let "G" represents gray seed colored peas while "g" represents white seed colored peas. Also, take note that "G" is dominant over "g". The ratio of gray vs white offspring is 202:198 and if we simplify it, it becomes 2:2. Thus, there are 2 times gray peas for every 2 white ones. Now as per Mendel's rule, the genotype of two gray peas would be GG and Gg So the genotype of parent would be GG x Gg.

Why meiosis is essential in sexual reproduction?

In regards to the importance of meiosis in sexual reproduction, we need to understand that meiosis is the chromosomal reduction process that enables the formation of the haploid germ cells required for sexual reproduction.

It also plays a crucial function in promoting genetic variety and making it easier for recombination to correct genetic flaws.

Therefore, Meiosis is a type of cell division that results in the making of four gamete cells as well as the halving of the number of chromosomes in the parent cell. To develop egg as well as sperm cells for sexual reproduction, this process is necessary.

In the 80s, 90s and early 2000s, the Chesapeake Bay was so polluted that fish and oyster populations were almost gone. In 2008, environmentalists were divided on how to fix the bay. Some demanded widespread seeding of sterile imported oysters to deal with worsening water quality that was wiping out aquatic life in the bay. Adding the imported oysters could slowly filter and clean the bay water. Others warned that this could be a disaster because a few of the imported oysters would be fertile and might proliferate, forcing out the last of the Eastern oysters or interbreeding with the native species.

How many carbon dioxide molecules are needed to produce a glucose during photosynthesis?.

Answers

Six carbon dioxide molecules are needed to produce glucose during photosynthesis.

What is photosynthesis?

A chemical reaction that takes place in photosynthesizing organisms such as plants, algae, and certain kinds of bacteria when they are exposed to sunlight. During the process of photosynthesis, water and carbon dioxide react to produce carbohydrates (also known as sugars), while also producing oxygen. Both animal and plant life require photosynthesis in order to survive.

It takes six molecules of CO2 to synthesize one molecule of glucose, and during this process, each molecule goes through its own individual C3 cycle. After six rounds of the Calvin cycle, one molecule of glucose is produced from six different molecules of carbon dioxide.
