Answer:

The answer is (d) (iv) and (v).

Explanation:

Soil bacterium Bacillus thruingiensis (Bt) produces proteins that kill certain insects like lepidopterans (tobacco dudworm, armyworm), coleopterans (beetles) and dipterans (flies, mosquitoes). Bacillus thuringinesis forms some intracellular protein crystals. These crystals contain a toxic insecticidal protein. The Bt toxin protein exists as an inactive toxin and is converted into an active form due to the alkaline pH of the alimentary canal that solubilities the crystals. The activated toxin binds to the surface of midgut epithelial cells and creates pores which cause cell swelling and lysis and finally cause the death of the insect.

So, the correct answer is '(iv) and (v)'.

Answer:

D.

Explanation:

When two organisms are in a mutualistic relationship, they benefit each other in a way that both rely on each other for survival in a particular environment. The elimination of one of them might have a negative effect on the survival of the other.

So also, the development of new resorts in the area which leads to the detsruction of the Hawaiian silverswords will therefore have a negative effect on the population of the honeycreeper. The population of the Honeycreeper will decrease because they rely on the silverswords for survival.

Answer:

Rudolf Virchow modified the cell theory and gave the concept of 'Omnis cellule e cellulae'- which means new cells develop by the division of the pre-existing cells. This is called the theory of cell lineage or common ancestry.

Explanation:

Based on their studies on cells, Schleiden and Schwann together formulated the cell theory. This theory however, did not explain as to how new cells were formed. Rudolf Virchow (1855) first explained that cells divide and new cells are formed from pre-existing cells (Omnis cellula-e-cellula). He modified the hypothesis of Schleiden and Schwann to give the cell theory a final shape. Cell theory as understood today is: (i) all living organisms are composed of cells and products of cells. (ii) all cells arise from pre-existing cells.

So, the correct answer is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'

Molecule X is an enzyme to which the starch is bonded and starch- enzyme complex is formed.

An enzyme is a type of protein that acts as a catalytic agent in chemical reactions. Enzymes play a crucial role in metabolism and other biological processes by increasing the rate at which chemical reactions occur.

Enzymes work by lowering the activation energy needed for a reaction to take place. In other words, enzymes make it easier for the reactants in a chemical reaction to come together and form products. This is accomplished by the enzyme binding to one or more of the reactants, known as substrates, and bringing them into a specific orientation that promotes the reaction. Once the reaction has taken place, the enzyme is free to bind to another set of substrates and catalyze the reaction again.

Enzymes are highly specific, meaning that each enzyme typically catalyzes only one particular reaction or a small group of closely related reactions. They are also highly efficient, able to catalyze millions of reactions per second.

its my first day going through the first cycle as a drop of water and it starts off with me going through evaporation. it feels.. misty and cozy at the same time. as i rise from the ocean i say goodbye to my brothers and sister who are soon to come. i next go through transpiration in which i transition into the cycle of condensation in which i'm with other follicles of water. we get bundled together until we are to heavy to lay adrift in the clouds. while dropping i land in a puddle in which we land in a puddle. once the cycle has stopped a deer manages upon us and cleanses itself. a little after the matter the deer runs, in which a bear approaches us and replenishes itself. once it releases the water we go through the cycle all over again.

Answer: Fossils are like biological documents. They prove the existence of species that are now extinct (like dinosaurs). They also show how different organisms that once lived on Earth lived, survived, and acted during different periods of the Earth's ancient, and even more recent history. Fossils can also help scientists and biologists reconstruct the evolutionary histories of present-day species.

Explanation: I hope this helps! Here's a picture of a species' fossils showing the species evolving over millions of years. ( I think it's a horse)

The population growth slows as size increases in the logistic model due to the density independent factors.

A density-dependent factor is any force that modifies the size of a population of living creatures in reaction to the population's density. Disease, competition, and predation are examples of factors that depend on density.

An element that has an impact on population size regardless of population density.

These density-independent factors consist of nutrient or dietary restriction, environmental contaminants, and harsh weather.

In logistic growth, a population's rate of per capita growth declines as it approaches the carrying capacity, a limit imposed by the environment's limited resources.

The variation in fundamental processes like natality, or the birth rate, mortality, or the death rate, as well as immigration and emigration, affects the population density in a particular ecosystem.

Answer:

e. On average, any allele may be lost because of the drastic reduction in population size from thousands to 10 for two generations

Explanation:

We have a new habitat for this population, on average this proportion could lose alleles since we have the given proportion of alleles to almost be the same and for the fact that there is a great decrease in the population population would not mean that a particular allele could survive into the next generation.

Answer:

Telomeres cap and protect the ends of chromosomes from degradation and illegitimate recombination. ... Abolition of telomerase activity in such cells nevertheless results in telomere shortening, a process that eventually destabilizes the ends of chromosomes, leading to genomic instability and cell growth arrest or death.
