The answer is triceps muscles. These muscles run along the back of the upper arm while the biceps run along the front. The triceps muscles allow the arm to extend at the joint of the elbow, therefore an antagonist of the biceps that bend the forearm.

Skeletal muscles whose primary function is an extension of a joint include joint in elbow, knee, shoulder, and hip. The movement including flexion, extension, abduction, and rotation.

<h3>Further explanation </h3>

Skeletal muscle also called voluntary muscles, it means it controlled consciously, for example walking, speaking, running and writing. Skeletal muscles are attached to bones by tendons, this muscle's contractions produce all the movement of the body parts. Skeletal muscle contraction also maintains body posture and position. In the simple word, here are four main functions of skeletal muscles:

to provide movement
to produce heat and energy for the
to maintains
to protects internal organs.

Skeletal muscle is any muscles that connect to and controls the motions of the skeleton, in the human body there are about 600 to 900 muscles, but we don't know the exact numbers. Many muscles are obscurely small or grouped with similar muscles. Biceps and triceps are an example of skeletal muscle. The biceps is the muscle on the inside of the arm above the elbow.

How do you read a Punnett Square?

Citrus2011 [14]

The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.

What happens to most zygotes with serious chromosomal problems?

Marrrta [24]

The answer is: They will not continue with pregnancy, if baby is born they rarely survive beyond early childhood.

Most of the zygote with serious chromosomal problem will be dead before labor. A big genetic problem will cause the baby unable to survive. Most of the abortion at the first trimester pregnancy is happen because of the chromosomal problem. If the baby survive till labor they will still have some health problems and most will not survive long.

which of the following is true about tertiary consumers compared to primary producers in a sunlight dependent ecosystem?

Yakvenalex [24]

Tertiary consumers produces less biomass but result in higher biomagnification.

<h3>What are different types of consumers?</h3>

Compared to primary consumers, tertiary consumers spend less energy. Organisms that eat secondary consumers are considered as tertiary consumers. Primary consumers are herbivores that devour plants. Consider insects. Secondary consumers are small carnivores that eat other animals, often herbivores. Consider frogs. Tertiary consumers are large carnivores that eat other animals, particularly secondary consumers. Consider birds. Bugs, frogs, and birds(First-tier consumers) The secondary market (Tertiary consumers).

The higher an animal is on the food chain (such as third-party consumers like seals), the higher the concentration of DDT in their bodies as a result of a process called biomagnification.

The ant, Myrmecia pilosula, is found in Australia and is named bulldog because of its aggressive behavior. It is particularly in

Inessa [10]

Answer:

The question lacks the illustrative diagram, the diagram has been attached as an image.

The correct answer, according to the picture is A.

Explanation:

All cells undergo division (mitosis or meiosis). Meiosis reduces the chromosomal number of the daughter cells by half. According to the question, The female species of Myrmecia pilosula ant has diploid cells total number of 2 chromosomes.

At the metaphase stage of meiosis I, homologous chromosomes (similar but non-identical chromosomes received from each parent) aligns at the center/equator of the cell called METAPHASE PLATE. This alignment is done when spindle fibres attach to the kinetochores of the chromosomes.

Option A in the diagram depicts this arrangement of homologous chromosomes in the centre of the cell. Note that, each chromosome has replicated to form SISTER chromatids held together at the centromere. These chromosomes will be pulled apart in the next stage (Anaphase).

Option B depicts only one replicated chromosome

Option D depicts separation of sister chromatids (only one chromosome)

Option E depicts separation of sister chromatids of two chromosomes which occurs in the Anaphase of meiosis II

What property of water allows it to stick to the sides of a vertical glass tube?

WINSTONCH [101]

The correct answer of the given question above would be CONDENSATION. The property of water that allows it to stick to the sides of a vertical glass tube is called condensation. When you see small drops of water that form on a cold surface, this process happens because the gas cools and becomes liquid. This happening is called condensation. Hope this answer helps.
