what experiments led to the discovery of dna as the hereditary material?

Answers

Answer:

In the 1920s, Frederick Griffith He was studying two different strains of a bacterium, called R (rough) strain and S (smooth) strain. He injected the two strains into mice. The S strain killed (virulent) the mice, but the R strain did not (non-virulent). Griffith also injected mice with S-strain bacteria that had been killed by heat. As expected, the killed bacteria did not harm the mice. However, when the dead S-strain bacteria were mixed with live R-strain bacteria and injected, the mice died.

function of nucleus, mitochondria ,endoplasmic reticulum, vacuoles ​

Answers

Answer:

nucleus...controls all the activities of the cell and carrries the genes

mitochondria..site for respiration that yields energy for the cell

endoplasmic reticulum... protein synthesis and lipids metabolism

vacuoles.... handle waste products and are responsible for regulation of osmotic pressure of a cell also

Explanation:

is this helpful?

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.

A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products.

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.

In an ecosystem, a deer consumes grass. What percentage of energy will the deer acquire from the grass? 0. 1% 1% 10% 100%.

Answers

In an ecosystem, the energy is transferred between the organisms participating in the food webs from producers and consumers.

The percentage of energy transferred to the deer after feeding on the grass is 10%.

The 10% law of the energy states that:

1. The food chain at each trophic level passes or transmits only 10% of the energy and 90% of the energy is lost as heat.

2. The amount of energy at each trophic level decreases, such that the producers if consuming the 100 J of energy, the deers or primary consumers at the first trophic level will have only 10% of the energy.

Thus, the deer will possess only 10% of the energy at each trophic level, following the 10% law.

The correct answer is Option C.

5. In a tundra ecosystem, the carrying capacity for arctic hares is about 400 individuals. Which of these events is MOST likely to reduce the carrying capacity for arctic hares in the ecosystem by at least 25 percent?

(A) a severe storm that kills about 100 adult and young arctic hares

(B) a 25 percent decrease in the populations of foxes, wolves, or other predators of arctic hares

(C) the arrival in the ecosystem of a species that competes with the arctic hare for its food

(D) a temporary increase in the arctic hare population to more than 425 individuals

(E) a mutation that introduces a new fur color to the arctic hare population

Answers

A temporary increase in the arctic hare population to more than 425

individuals.

Hares are among the primary consumers as they are herbivores while foxes

are  secondary consumers which feeds on the hares.Foxes will hunt the

hares for food which will drastically reduce their population

Increasing their population by 425 individuals with the hares having a

population of 400 will surely decrease their carrying capacity in the tundra

ecosystem.

In the area illustrated, what process is evident over time?

Answers

In the area illustrated in the image attached, the biological process which is evident over time is: ecological succession.

Ecology can be defined as the scientific study of the relationship existing between living organisms such as plants and animals with respect to their physical and biological environment (abiotic factor).

In Ecology, ecological succession refers to a process through which the structure of an ecological (biological) community evolves or changes over time.

Generally, there are three (3) main types of ecological succession and these include:

Primary successionSecondary successionCyclic succession

From the ecological (biological) community illustrated in the image attached, we can deduce that there is an evolution (change) in the species of plants growing over time. This ranges from weeds during the first visit to pine and oak trees during the seventh visit.

How does a forest fire impact a population of birds that nest in the trees.

Answers

Answer:

If a forest fire occurs it will impact a population of birds that nest in those trees because their habitat will be burnt down. This will provoke the birds to find a new habitat which can be hard if the entire forest is burnt down. Additionally resources such as food will be burned down as well.

Assuming birds escape a fire, smoke might still affect their health in ways that aren’t very well understood. Scientists have found that smoke can damage lung tissue and leave the animals susceptible to potentially lethal respiratory infections.

Answer:

Wall of stomach : it has three layers of muscle instead of two. Under these muscle layers is the adventitia, layers of connective tissue continuous with the omenta. The epithelium of the stomach forms deep pits, called fundic or oxyntic glands.

wall of ileum : The wall itself is made up of folds, each of which has many tiny finger-like projections known as villi on its surface. The ileum has an extremely large surface area both for the adsorption of enzyme molecules and for the absorption of products of digestion.
