Somatic cells of roundworms have four individual chromosomes per cell. How many chromosomes would you expect to find in an ovum

from a roundworm?

Answer:

2 chromosomes

Explanation:

The cell of an eukaryotic organism like roundworm contains the Nucleus, which harbors the genetic material embedded in the chromosome. The number of chromosomes of that organism is contained in each cell.

Somatic cells, also called body cells, are all other cells asides sperm and eggs, that form the tissues and organs of an organism. Somatic cells are usually diploid i.e two sets of chromosomes from each parent. In this question, the roundworm has 4 chromosomes in its somatic cell.

The reproductive cells or sex cells (sperm and eggs) of an organism always result from meiotic division of specialized cells.

Since meiosis is a kind of division that results in cells with their chromosome number reduced by half (haploid), it therefore means that the ovum and sperm cell will be expected to contain 2 chromosomes each.

This way, when fertilization occurs (sperm and egg fusion), the resulting zygote, which will eventually develop into an adult organism, will have 4 chromosomes.

Ksju [112]

Answer:

Option D

Explanation:

Cyanobacteria preserve its photosynthetic pigments in the thylakoids which allows masking of green of chlorophyll a and other accessory pigment i.e phycobiliproteins (phycocyanin, allophycocyanin and phycoerythrin).  

Chlorophyll a is mainly responsible for harvesting light for photosynthesis. Phycocyanin is blue in color, allophycocyanin is blue in color  and phycoerythrine is red in color. These together harvest light in the green, yellow and orange part of the spectrum which cannot be used by other phytoplankton species

Hence, option D is correct

grandymaker [24]

Answer: See explanation

Explanation:

When volcanic eruptions occur, there are a lot of magma i.e. molten rocks that are formed under the volcano. This formation of the magma and their movement is referred to as magmatism. The magmatic process has an impact on the way magma melts.

Magmatism can be used as an acronym in the following way:

M - Molten

A - Assimilation

G - Geology

M - Mountain

A - Active volcano

T - Tectonics

I - Igneous

S - Seismograph

M - Melting

Slips, trips, and falls account for many general industry injuries. In areas where wet working conditions exist, placing grates
cestrela7 [59]

Answer: slip

Explanation:

The slip may occur while working on surfaces that are slippery because of wet and oily processes occurring at the workplace. The practices like floor cleaning, debris left on the floor and leakage of material can cause slips. The slip will occur when the floor provides a limited friction for walking.

The trip may occur while walking on the uneven floor. This may occur when the person's foot hit the objects that come in contact while walking. This disturbs the balance of the person while walking.

The slip and trip both can result in fall. This happens when the body gets deviated from the center of balance.

According to the given situation, a slip will occur as the working conditions are wet and the grates on the floor will slip due to lack of friction between the floor and the grates.
