Is the Use of energy to move particles against the concentration gradient

Answers

Answer:

During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

Which is an example of genetic drift?

Answers

Answer:

Explanation:

Genetic drift, gene flow, mutations, and natural selection are responsible for the change in the gene pool over time. Example of genetic drift: a population of rabbits with alleles B and b, both alleles are present in equal frequencies p = 0.5 and q = 0.5 if 10 parents reproduce the probability of having an offspring with alleles B or b is 0.5; however, by chance, a slight difference in the offspring allele frequency might occur due to random sampling. As a result, in the next generation, the allele frequencies will change slightly to new frequencies by chance to become p = 0.4 and q = 0.6. in the following generations, the random sampling of alleles continues and the change in allele frequency will be greatly different from the initial 0.5 frequency due to genetic drift. Even though genetic drifting is one of the factors that participate in the evolutionary process of the genetic pool by increasing or decreasing a certain allele’s frequency, however, it does not influence the adaptation of individuals to the environment since the affected genes may be harmful or beneficial genes.

Answers

Answer:

Decrease the pumping of NADPH across the thylakoid membrane

Decrease of flow of electrons from photosystem II to photosystem I

Explanation:

Thylakoids are defined as a membrane-bound compartments located inside the chloroplasts and the cyanobacteria. Here, light-dependent reactions of photosynthesis occurs.

To block the photosynthesis process, the herbicides pushes the dichlorophenyl dimethylurea to block the electron flow through the photosynthesis II and it reduces the flow of electrons from photosystem II to photosystem I. It also decreases pumping of the NADPH across the thylakoid membrane.

Conjugation differs from reproduction because conjugation Group of answer choices transfers DNA horizontally, to nearby cells without those cells undergoing replication. transcribes DNA to RNA. replicates DNA. transfers DNA vertically, to new cells. copies RNA to make DNA.

Answers

Answer:

it is differs from reproduction because conjunction group of answers

Conjugation transfers DNA horizontally, to nearby cells without those cells undergoing replication.

Conjugation is a mechanism of genetic transfer in bacteria where genetic material, usually in the form of plasmids, is transferred from one bacterial cell to another. Unlike reproduction, which involves the replication and inheritance of genetic material through cell division, conjugation allows bacteria to transfer genetic material horizontally between cells that are in close proximity to each other.

During conjugation, the donor bacterial cell containing the plasmid makes contact with the recipient cell through a specialized structure called a pilus. The plasmid DNA is then transferred from the donor cell to the recipient cell through this pilus. The transferred DNA can include genes that provide advantages such as antibiotic resistance or the ability to metabolize certain substances.

The key difference between conjugation and reproduction is that conjugation does not involve replication of the recipient cell's entire genome. Instead, it transfers specific genetic material from one cell to another. The recipient cell does not undergo replication as a result of conjugation but acquires new genetic information from the donor cell.

Reproduction, on the other hand, involves the replication and inheritance of the complete set of genetic material in the parent cell. It results in the production of offspring cells that are genetically identical or similar to the parent cell.

In summary, conjugation is a form of genetic transfer in bacteria where DNA is horizontally transferred between cells without those cells undergoing replication. It allows for the exchange of genetic material and the acquisition of new traits by recipient cells. Reproduction, on the other hand, involves the replication and inheritance of genetic material through cell division.

What happens during S phase?

O A. Chromosomes are duplicated.

O B. DNA separates into two nuclei.

O C. The cell splits in two.

O D. Cytoplasm is manufactured.

Answers

Answer: A. Chromosomes are duplicated.

Explanation: This is the correct answer on the quiz.

Chromosomes are duplicated in S phase. Therefore, option (A) is correct.

What do you mean by S phase?

Between G1 phase and G2 phase, DNA replication takes place during S phase of the cell cycle. The processes that take place during S-phase are tightly controlled and highly conserved.

The cell replicates its genetic material entirely during the S phase of DNA synthesis; At the end of S phase, a normal diploid somatic cell with a DNA complement of 2N acquires a DNA complement of 4N.

DNA synthesis or replication occurs during the S phase of the cell cycle, which occurs prior to the interphase. Before entering mitosis or meiosis, the cell's genetic material is replicated in this manner, leaving enough DNA for daughter cells to divide.

Answers

Answer: Gene that arose through gene duplication, but by acquiring mutations became nonfunctional.

Explanation:

A gene is a functional unit of heredity formed by DNA. They possess a sequence of nitrogenous bases that during translation is read by ribosomes to produce molecules called proteins.  A pseudogene is a DNA sequence that resembles a gene, but which has been inactivated in the course of evolution by mutations in its sequence. Thus, it is a gene that derives from other known genes and whose functions are different, may have lost their functionality or have radically changed it. To this day, it is not known exactly how pseudogenes are created, however some theories are as follows:

1. A gene duplication can generate two copies of a gene when only one is needed. A mutation would then occur that deactivates one of the copies. In addition, the duplication event may not be complete, so that the copy has incomplete promoters.  

2. They may be fragments of the messenger RNA transcript of a gene may be spontaneously reverse transcribed and inserted into the chromosomal DNA. They lack the promoters of normal genes, so they are not expressed normally.

3. A gene may become non-functional or inactivated if such a mutation becomes fixed in the population. This can occur by normal means such as natural selection or genetic drift.

Which inference can you make about why finches have adapted different beak sizes and shapes? (1 point)
They are different species.
O They live in the same location.
O They eat different foods.
O They have a wide range of variation

Answers

Finches have adapted different beak sizes and shapes because they eat different foods. So the correct option is C.

What is natural selection?

Natural selection is a mechanism for evolution to happen. It is the process by which living organisms acquire certain characters according to their needs.

It is important to understand natural selection to understand the essential concepts of the processes by which living organisms have been able to develop the complex structures which are helped them to survive.

Natural selection results from various conditions of environment, ecosystem and heredity. An example of natural selection is the development of antimicrobial resistance to pathogens.

Finches are known to have developed different sizes and shapes of beaks according to the kind of food that they eat. If they fed on insects, they had long and pointed beaks. If they fed on seeds and nuts, they had broad and blunt beaks.

Therefore the correct option is B.

Metallic bonds are responsible for many properties of metals, such as conductivity. Why is this possible? (1 point)
O Metals have low electronegativity, so they are conductive because they pass charges easily.
OTwo metals bonded together are going to be more conductive than a metal bonded with a nonmetal.
O The bonds can shift because valence electrons are held loosely and move freely.
O An attraction between a positive charge and a negative charge is created.

Answers

The correct answer is;  Metals have low electronegativity, so they are conductive because they pass charges easily.

Metals are found towards the left hand side in the periodic table. They are known for their low electronegativity. Metals are electropositive. This means that they loose charges(electrons) easily.

A metallic bond is comprised of positively charged metallic ions and a sea of electrons.These electrons can move freely.

This sea of electrons are the charges that are responsible for the properties of metals such as high conductivity.
