A Researcher Is Investigating The Of Effects A Chemical That Makes Thylakoid Membranes Permeable To Hydrogen

Answers

Answer 1

Answer:

B. The chloroplasts will generate less ATP

Explanation:

Photosynthesis, occurs in the chloroplasts of plants. Solar energy is converted into chemical energy in the form of stable carbohydrates.  

              6 CO2 + 6 H2O + light  →  C6H12O6 + 6 O2

Carbon Dioxide + Water + Light       Glucose + Oxygen

Chloroplasts, are small membrane-bound organelles of multi-folded membranes containing pigments, enzymes, and other molecules that facilitate the process. The thylakoid contains multiple folded membranes called granum stacked together. They contain light-absorbing pigments like chlorophyll.  

Here, absorbed light is  used in photolysis, to split water produce H+, O2 and high-energy electrons for the high-energy producing electron transport chain.  

Protons are pumped into the stroma within granum, producing ATP.                 ∴ Without ATPase, less ATP is produced.

Answer 2

Chloroplasts are the membrane-bound organelles, which carry out the process of photosynthesis. The correct answer is:

Option B. The chloroplasts will generate less ATP.

Photosynthesis is the process of preparing the food in presence of sunlight. It occurs in the plant. The chloroplasts are the membrane-bound organelles, which consists of pigments, enzymes, and other molecules. The thylakoid membrane consist of stacked membranes, known as grana. The light-absorbing pigment, chlorophyll is found in grana.

The following points can be used to explain photosynthesis:

The absorbed light initiates photolysis, which is the breakdown of water molecule into hydrogen and oxygen. During photolysis, high-energy electrons are also released. These electrons are utilised in the electron transport chain to provide energy.

Therefore, the permeability of the protons into the granum will yield ATP. The less ATP will be produced without ATPase.

Why is meiosis important in maintaining genetic diversity?

Question 6 options:

A Meiosis creates diversity by cutting each chromosome exactly in half.


B The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.


C It creates sex cells (eggs or sperm) that have exactly the same alleles (version of a gene) as the parents.


D The chromosomes in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy.

Answers

Answer:

We now know that meiosis is the process of chromosomal reduction which allows the production of haploid germ cells necessary for sexual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.

Explanation:

Brainliest please?

Meiosis is a specialized form of a cell division in which number of chromosomes is reduced to half. The reduction in chromosome number is achieved by one round of DNA replication and two rounds of chromosome segregation.    

Meiosis produces genetic variation by the process of recombination.Recombination occurs when two molecules of DNA exchange pieces of their genetic material. The process of recombination occurs during the prophase stage of meiosis I. In meiosis, crossing over occurs between the non-sister chromatids in a homologous pair (one from each parent) of chromosomes.

The correct answer is option B. The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.

Other options-

A. Meiosis creates diversity by cutting each chromosome exactly in half - incorrect .In meiosis the chromosome number is reduced to half.

C. It creates sex cells (egg or sperm) that have exactly the same alleles (version of a gene) as the parents-incorrect. The sex cells produced are not genetically identical to the parent cell.

D. The chromosome in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy-incorrect. In meiosis the chromosomes are not exactly copied.

Which biomolecule provides the instructions to build enzymes?
A. Carbohydrates

B. Lipids

C. Nucleic acids

D. Proteins

Answers

The correct answer is D. Proteins

Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur everywhere in life.

Hope this helps :D

Proteins are the building blocks of enzymes, and proteins are made up of amino acids that are linked together in one or more polypeptide chains. Therefore, option (D) is correct.

What are enzymes?

Enzymes are proteins that aid in the acceleration of metabolic processes, also known as the chemical reactions that take place in our bodies. They are responsible for the creation of some chemicals while also decomposing others. Enzymes are present in everything that is alive. Enzymes are something that are produced by our bodies spontaneously.

Enzymes regulate most biochemical reactions in animals, plants, and microbes, thus there are many examples. Animal digestive enzymes are well-known. Gastric juices break down food with the enzyme pepsin. Salivary amylase turns starch into sugar, starting digestion.

I converted from kg to g because it is the standard.

Explanation:

a constant net forced of 150 N is exerted to accelerate a cart from rest to velocity of 45 m/s in 8 seconds.what is the mass of the cart?​

Answers

Answer:

The mass of the cart is 26.7 kg.

Explanation:

To find this answer use the formula for acceleration first to find how fast the object had to be acccelerating to gain a velocity of 45m/s in 8 seconds flat.

Here's the formula for acceleration:

a = V- V₀ ÷ T (Wher V = final velocity; V₀ = Initial velocity, and T = time)

Plug all known values into the equation and you get -

a = (45m/s - 0m/s) ÷ 8 , which works out to 5.625 m/s²

Once you have this value then you place it into the equation for finding an object's mass, and that formula is:

M = [tex]\frac{F}{a}[/tex]  or M = [tex]\frac{150N}{5.625m/s^{2} }[/tex]

This works out to  26.6667 kg or approx. 26.7 kg if you are asked to round it to three significant figures.

The probability that the leopards will have an offspring that is sassy and timely is 3/16

This question involves two different genes. The allele for being shy (S) is dominant to the allele for being sassy (s) in the first gene while the allele for being timely (T) is dominant to being tardy (t).

According to this question, A female leopard that is heterozygous for both the S and T traits i.e. SsTt mates with a male leopard that is also heterozygous for both traits i.e. SsTt

The two heterozygous leopards (SsTt) will produce the following gametes: ST, St, sT, and st

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

S_T_ = shy, timely (9)S_tt = shy, tardy (3)ssT_ = sassy, timely (3)sstt = sassy, tardy (1)
