Answer:

A-Carbon

B-Nitrogen

Explanation:

Compost or soil made from composting provide contain nutrients that are required for the growth of the plants. Compost is known as organic fertilizer and soil conditioner of nature for plants.

Rich soil from composting consist of waste from kitchen and yard, having carbon and nitrogen rich waste. Carbon in compost act as energy source of of microbial cells and nitrogen is a component of nucliec acid and amino acid and they both together are very important for plants and life in general.

Hence, the correct answer is "A-Carbon and B-Nitrogen".

Answer:

Peter is viewing a prepared slide with the 40X objective. His view is

shown below. Unfortunately, the label in the slide has been torn off,

so he is not sure what he is looking at. Based on his observation

alone, can Peter identify the type of organism that these cells come

from? Why or why not?

Yes, Peter will identify identify the organism as label would not deter its identification. Reason being that diagram without labeling would not nullify identification of my organism

In 1985 a biologist counted 750 pine trees in a 250 hectare forest. Using similar counting techniques, the biologist counted 1,2

Alisiya [41]

Answer:

Suppose that we have a given function f(x)

The average rate of change of the function between two values x₁ and x₂ is given by:

$r = \frac{f(x_2) - f(x_1)}{x_2 - x_1}$

a) We want to find the average (rate) of change on the size of population from 1985 to 1995.

We have that:

f(1985) = 750

f(1995) = 1500

Then we have:

$r = \frac{1500 - 750}{1995 - 1985} = 750/10 = 75$

This means that the population of trees increases, in average, at a rate of 75 trees per year.

b) What is the density of trees each year that they were counted?

This will be equal to the quotient between the number of trees and the area.

1985: number of trees = 750 pines

area = 250 ha

Then the density is:

D(1985) = (750 pines)/(250 ha) = 3 pines/ha

So 1985, there were 3 pines per hectare.

1990: number of trees = 1250 pines

area = 250 ha

Then the density is:

D(1990) = (1250 pines)/(250 ha) = 5 pines/ha

1995: number of trees = 1500 pines

area = 250 ha

The density is:

D(1995) = (1500 pines)/(250 ha) = 6 pines/ha

3) now we want to get the average change between 1985 and 1995 in the density, this will be:

$r = \frac{D(1995) - D(1885)}{1995 - 1985} = \frac{6 pines/ha - 3pines/ha}{10} = 0.3 pines/ha$

So, on average, each year the number of pines per hectare increases by 0.3

Why are viruses considered as peculiar microorganisms? <br><br><br><br><br> Plese answers

Aleksandr [31]

Answer:

Because they can only reproduce in a living cell

Explanation:

Virus is an organism that is incapable of replicating on its own without a living host. A virus infects a living host and makes use of Its replicational ability to produce new virions. A virus consists of a genetic material surrounded by a Protein called CAPSID. It does not possess the characteristics of other living organisms.

This means that it does not carry out any of the features a living cell undergoes e.g reproduction, respiration etc. Due to this reason, it is not classified as a living thing. They don't possess organnelles that carry out this peculiar functions.

A virus is considered a peculiar microorganism because it can only live and reproduce in a living host cell.

Serhud [2]

Over the past four decades, researchers have identified many types of oncogenes, including growth factor receptors, transcription factors, and intracellular signaling proteins.

<h3>What are oncogenes?</h3>

These are specific genes in an organism that can cause the formation of cancer. These genes are prone to defects that when activate, signal for a cell to become a tumor. The genes listed in the question are some examples of the types of cells that can be oncogenes.

Therefore, we can confirm that over the past four decades, researchers have identified many types of oncogenes, including growth factor receptors, transcription factors, and intracellular signaling proteins.
