Answer:

This question is incomplete as it lacks statements, the statements and the answers are as follows:

occurs in organisms that sexually reproduce - MEIOSIS

occurs during growth and development - MITOSIS

the DNA is replicated - MITOSIS AND MEIOSIS

occurs in all organisms - MITOSIS

the number of chromosomes remains the same - MITOSIS

the number of chromosomes reduces by half - MEIOSIS

Explanation:

Meiosis and mitosis are both types of cellular divisions that occur in living cells. Mitosis involves the formation of two (2) daughter cells that are genetically identical to the parent cell while meiosis involves the formation of four (4) daughter cells that are genetically different from the parent cell.

The following are characteristics of the two division processes based on this question:

MITOSIS:

- It occurs during growth and development of an organism.

- it involves DNA replication

- it occurs in all organisms since every living organism undergoes growth and development.

- the number of chromosomes after mitosis remains the same in the daughter cell i.e. 2n remains 2n

MEIOSIS:

- It occurs only in organisms that sexually reproduce.

- it also involves the replication of DNA

- The number of chromosomes in the daughter cells is reduced by half i.e. 2n to n.

Revolutionary War soldiers made their own musket balls by melting lead (Pb). How much energy

Sati [7]

Answer:

Q = 813.12 j

Explanation:

Given data:

Mass of lead = 21 g

Initial temperature = 25°C

Final temperature = 327.5°C

Amount of heat absorbed by lead = ?

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = T2 - T1

ΔT = 327.5°C - 25°C

ΔT = 302.5°C

Specific heat capacity of lead = 0.128 j/g.°C

Q = m.c. ΔT

Q = 21 g. 0.128 j/g.°C.302.5°C

Q = 813.12 j

Bacteria are organisms that need to be viewed with a microscope Darla designed a model of bacteria using household

levacccp [35]

Answer:

She was able to represent something small in a larger way.

Explanation:

Obviously if the bacteria need to be viewed with a microscope, they are extremely small. Darla likely does not have access to a microscope at her house, so using the macaroni and string, she made her own way of "seeing" the bacteria, but in a larger way. B is false because bacteria are small, not large. C is false macaroni do not need to be viewed with a microscope; in fact, this will probably allow you to not see them very well at all. D is false because macaroni wouldn't really show any patterns.

mestny [16]

Melanoma is the type of cancer Mary Lou had, Sunburns in adulthood assume to be the mostly associated with melanoma. Melanoma, the most severe type of skin cancer, develops in the cells (melanocytes) that produce melanin — the pigment that gives your skin its colour. Melanoma can be also apear in your eyes and, rarely, in internal organs, such as your intestines.

How can we bring back lost nutrient in the soil without direct application of fertilizer?

bazaltina [42]

Answer:

Explanation:

Crop rotation

Rotation of crop is important to help conserve nutrients that are available in the soil and prevent total use up of the nutrients. The same type of plants all year round on the same soil keeps on draining the land of the same nutrients needed for their growth. Rotation of different can help maintain soil nutrients level as some crop fixes nutrients in the soil.

Natural mulching

The use of cover cops as mulch helps protect the soil and allows for retention of nutrients. When cover crops are harvested the leaves can be turned back into soil to release nutrients that are stored up in the plant part.

Composting is the process of decomposing organic matter this could include animal waste such as dung,leaves both green and dead, kitchen. This waste are stored up, little water is added to moist and then allow to decompose it can be mixed together after few days to aerate after. After decomposing to form compost it can be added to the soil. It is usually rich in nutrients.
