Answer:

3. They digest food externally.

4. They can absorb nutrients from food, even though they lack digestive enzymes.

Explanation:

Fungi are nutritionally heterotrophic, they may be saprophytes, parasites or some are symbionts.

Most of the fungi are saprophytes and get their nutrition by absorbing organic compounds from the environment.

The hypha of the fungus have high surface-area-to-volume ratios so, they are well adapted to absorb nutrients from their environments.

The fungal hypha release of hydrolytic enzymes in the external medium which breaks down large organic molecules such as carbohydrates proteins and fats into smaller molecules. These simple molecules are then absorbed as nutrients into the fungal hyphae.

mr Goodwill [35]

The question is incomplete as it does not have the options which are:

(a)DNA (b)tRNA (c)rRNA (d)mRNA

Answer:

Option-mRNA

Explanation:

The mRNA is synthesized from the DNA and which is also a type of nucleic acid. When the nucleic acid is extracted from the yeasts and then mixed with the resin beads to which the polynucleotide with thymine base oar is attached.

The mRNA will bind to the resin bead as the mRNA after synthesis undergoes modification and attaches poly A tail to the end of the mRNA at 3' end.

This poly-A tail has adenine which easily binds to the thymine and thus mRNA easily attaches to the resin bead.

Thus, mRNA is correct.

What is the cost and the core of a virus made of

Lisa [10]

Viruses are made of one or more nuclei acid molecules surrounded by a coat protein or capsid. So the core of the virus will contain the viral genome. Some viruses' capsid maybe enclosed with an envelope derived from the host cell (the cell that the virus is infecting), and this envelope is also derived from the host cell membrane.

sladkih [1.3K]

Answer:

a. parasitism:

The parasite benefits by harming the host e.g hookworms and humans

b. commensalism

In this association, one species benefits while the other is unaffected (its not harm and dies not benefit) e.g. epiphytic orchids and trees

c. mutualism

Here, both species benefit as seen in rumen bacteria and cows

Explanation:

Parasitism = +/- relationship

The predator benefits by harming the host. E.g. hookworms and humans. The hookworm (parasite) eat man blood while man (host) loses blood to it.

Commensalism = +/0 relationship

One specie(s) benefits while the other specie(s) neither benefits nor is harmed. E.g. epiphytic orchids live on tree branches or tree trunks as it's habitat or shelter while the trees neither benefits nor is harmed

Mutualism = +/+ relationship

Both organisms benefit in this relationship. E.g. rumen microbes aids grass digestion in cows, while the microbes benefit as it obtain steady food or nutrient from the cow

Assuming that other factors are equal, how are the birthrate and death rate

igor_vitrenko [27]

Answer:

In a stable population, if all the other factors are equal then the birth rate should be equal to the death rate in order to maintain the stability.

Explanation:

The birth rate is described as the number of births taking place in an area per year. Death rate is described as the number of deaths taking place in an area in a year.

In order to maintain a stable population, the birth rate should be equal to the death rate. If there are more number of births than the number of deaths, then it would mean more competition for resources like food, water etc.
