According to evolutionary theory, behaviors that optimize survival and reproduction are favored by natural selection and therefore more likely to persist. How, then, can we explain the evolution of altruism, which is by definition costly to the self

Answers

Answer 1

Answer:

Altruism could be helpful for the survival of relatives

Explanation:

Altruism behavior is produced when an organism decreases its fitness in order to increase the chances of survival in other individuals in the population. It is believed that altruistic behavior could have evolved as an adaptation associated with the survival of relatives from the same family. In consequence, if this were the case, altruism could ultimately be considered as a selfish behavior because it aims at passing on of genes through the survival of relatives which could benefit with this behavior.

What are the functions of mitotic cell division?

Answers

Answer:

The main functions of mitosis are growth and repair. Some cells once fully formed do not undergo cell division, such as nerve cells and muscle cells. Since you can never re-grow or repair these types of cells once they are mature, you must take care of the ones you have.

Explanation:

Mitotic cell division is a process of mitoses where a parent cell divides to create two identical daughter cells.

Explain why ecological succession occurs.

Answers

Ecological succession occurs due to the changes in physical environment and population of species. In an ecosystem, a species requires a particular set of environmental conditions under which they grow and reproduce.

Ecological succession occurs due to the changes in physical environment and population of species. In an ecosystem, a species requires a particular set of environmental conditions under which they grow and reproduce.

What is an Ecological succession?

Ecological succession is the process by which plant communities develop over a period of time on the land where there was no vegetation.

The succession begins with a pioneer species such as lichens, some fungi species. Species such as lichen begins to secrete acids that begin to break the barren land into small particles.

The small particles mix with lichen remains and starts soil formation.

Thus, Ecological succession occurs due to the changes in physical environment and population of species.

Answers

Answer:

Explanation:

Carnivorous plants are plants that derive some or most of their nutrients (but not energy, which they derive from photosynthesis) from trapping and consuming animals or protozoans, typically insects and other arthropods. Carnivorous plants have adapted to grow in places where the soil is thin or poor in nutrients, especially nitrogen, such as acidic bogs. Charles Darwin wrote Insectivorous Plants, the first well-known treatise on carnivorous plants, in 1875. Carnivorous plants can be found on all continents except Antarctica, as well as many Pacific islands.

Not one of the ways that bacteria have adapted to become resistant to antimicrobial agents.

Answers

Answer:

Explanation:

An antimicrobial agent is a natural or synthetic chemical that kills or inhibits the growth of microorganisms. Bacteria have a mechanism of transferring genomic material called horizontal gene transfer, the movement of genes between cells that are not direct descendants of one another. Horizontal gene transfer allows cells to quickly acquire new characteristics and drives metabolic diversity. One of the characteristics usually acquired is the resistance to antibiotics.

Three mechanisms of genetic exchange are known in prokaryotes:

(1) transformation, in which free DNA released from one cell is taken up by another; (2) transduction, in which DNA transfer is mediated by a virus; and (3) conjugation, in which DNA transfer requires cell-to-cell contact and a conjugative plasmid in the donor cell.

Examples of genes transferred by transducing bacteriophages include multiple antibiotic resistance genes among strains of Salmonella enterica serovar Typhimurium, Shiga-like toxin genes in Escherichia coli, virulence factors in Vibrio cholerae, and genes encoding photosynthetic proteins in cyanobacteria.

Conjugative plasmids use a mechanism to transfer copies of themselves and the genes they encode, such as those for antibiotic resistance, to new host cells.

What was the dependent variable in Drew's experiment? the lake that Drew observed the depth at which Drew found the algae the amount of algae measured the sky conditions on a particular day

Answers

Answer:

The depth at which Drew found the algae

Explanation:

The dependent variable was the depth at which he found the algae, because that is what he measured on each day.

The independent variable was the sky conditions, since that changed from clear to cloudy, which impacted the dependent variable/the depth of the algae.

Answers

Answer: interfering with the normal transmission of nerve impulses to the posterior pituitary

Explanation: A blow to the head may cause diabetes insipidus by interfering with the normal transmission of nerve impulses to the posterior pituitary. Interfering with the normal transmission of ADH (antidiuretic hormone) to the posterior pituitary is done via the axons of the hypothalamic neurons. The disease is a rare one, characterized by the excretion of large amounts of severely diluted urine which cannot be reduced when fluid intake is reduced. It is generally related to a tumor or an insult to the pituitary gland, where the hormonal signals it gives to the kidneys break down, and the kidneys do not conserve water, but express the water as urine.

Which of the following processes do not take place in the mitochondria? a) citric acid cycle b) conversion of pyruvate to activated acetyl groups c) oxidation of fatty acids to acetyl CoA d) glycogen breakdown

Answers

Answer:

D

Explanation:

The breaking down of glycogen-glycogenolysis takes place in the cytosol of cells of the liver and muscles.it is the compensatory process for providing glucose depleted cells with extra glucose. It is the opposite of Glucogengenesis the formation of glycogen in cells.

it involves the activities of enzymes glycogen phosphorylase which catalysis the removal of alpha1-4glycosidic bonds from the glycogen molecules.Thus freeing the glucose molecules from the glycogen while retaining the 1-6 glycosidic bonds.

Its stimulation is by  epinephrine hormone.while  the hormones glucagon from the pancreas control its release into the blood stream,Thus the low levels of glucose in the blood stream caused glucagon to initiate  the breakdown of glycogen in the liver and muscles down to glucose.As the level of this rise in the blood stream Insulin stimulates the entry of the glucose into the cells reducing the levels of blood glucose,inhibiting glucagon levels ,and therefore stopping Glycogenolysis.

The correct answer is option A. "EF-G"

Explanation:

As its name implies, the elongation factor (EF-G) of E. coli is one vital protein that participates during the elongation phase of translocation. EF-G catalyzes the GTP-dependent ribosomal translocation step, which allows the ribosome to change from its pre-translocational to the post-translocational state, moving the process from the P to the E site of the ribosome.

Answers

Answer:

D, Physical

Explanation:

Linnaean classification uses visible physical features. It has a kingdom-to-species taxonomy. Each species has a distinct two-word Latin name. Therefore, option (D) is correct.

What is Linnaean system of classification?

The Linnaean system classifies organisms according to their outward morphological and behavioural similarities. A hierarchy of taxonomic levels, from the kingdom down to the species, makes up this structure. A distinct, two-word Latin name is bestowed for each and every species.

Carl Linnaeus, the "Father of Taxonomy," named and organised species. His hierarchical categorization scheme and binomial nomenclature system were major advances to taxonomy (two part naming method). The Linnaean system organises organisms into Kingdom, Phylum, Class, Order, Family, Genus, and Species. Latin names are global. A species' scientific name includes its genus. Italics or underlining cover the name. Humans, for instance. It's Homo sapiens.

Molecule that contains the information for the growth and functioning of the cell

Answers

Answer:

Cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell is often a complete organism in itself, such as a bacterium or yeast. Other cells acquire specialized functions as they mature. These cells cooperate with other specialized cells and become the building blocks of large multicellular organisms, such as humans and other animals. Although cells are much larger than atoms, they are still very small. The smallest known cells are a group of tiny bacteria called mycoplasmas; some of these single-celled organisms are spheres as small as 0.2 μm in diameter (1μm = about 0.000039 inch), with a total mass of 10−14 gram—equal to that of 8,000,000,000 hydrogen atoms. Cells of humans typically have a mass 400,000 times larger than the mass of a single mycoplasma bacterium, but even human cells are only about 20 μm across. It would require a sheet of about 10,000 human cells to cover the head of a pin, and each human organism is composed of more than 30,000,000,000,000 cells.
