If a cell synthesizes large quantities of protein molecules, which organelles might be numerous in that cell?

Answers

Ribosomes, because they produce protein for the cell. 

Answer:

The correct answer will be- ribosomes

Explanation:

The organelle associated with the synthesis of the protein molecule is known as the ribosomes which provide the site for the process of translation.

The organelle is composed of rRNA and the lipoproteins arranged in the two subunits: the larger subunit and the smaller subunit.

Both the subunit contains the complexes which translate the codings of the mRNA and translate them to amino acid through tRNA and form peptides.

Thus, ribosome is the correct answer.

Why are size and complexity limited in organisms with colonial or filamentous growth forms?

Answers

Size and complexity are limited in systems usually by a combination of factors. Such as access to resources. Successful reproduction. Evolution over time dictates what is a successful balance in size and complexity in a system in its environment. If the resources are there and there is successful adaptation to the environment, systems can be supported that are extremely complex and also huge in size. Say the human body as a system.

Which muscle is not part of the rotator cuff?

Answers

The four muscles of the rotator cuff are the supraspinatus, infraspinatua, teres, and subcapularis. Hope this helps!
Final answer:

The deltoid muscle, among others like the rhomboids and latissimus dorsi, are not part of the rotator cuff. The rotator cuff consists of the tendons of four specific muscles: the deep subscapularis, supraspinatus, infraspinatus, and teres minor.

Explanation:

The rotator cuff is an important component of the shoulder joint formed by tendons of four muscles, specifically the deep subscapularis, supraspinatus, infraspinatus, and teres minor. These muscles arise from the scapula and attach to the humerus, providing essential structural support and allowing a range of movements. However, the deltoid muscle, which originates on the scapula, is not a part of the rotator cuff though it plays a significant role in the motion of the shoulder, facilitating actions such as flexing, medial rotation, extension, and lateral rotation of the arm.

Other muscles that are not part of the rotator cuff, but vital to the movement of the upper limb, include the rhomboids, trapezius, latissimus dorsi, brachioradialis, extensor carpi radialis, and extensor digitorum amongst others. While these muscles contribute to the flexibility and strength of the upper limb, they do not form the rotator cuff.

How does the central vacuole of a plant cell allow the plant to stand up right wilt?

Answers

Large centrally located vacuole is the characteristic feature of a plant cell. It is a single membrane bound sac like structure that provide structural support to the cell. It also controls turgor pressure. It stores water inside that keeps the plant to stand still. When the plant is fully hydrated, the central vacuole is filled with water and the membrane of the vacuole pushes against the cell wall. this increases the turgor pressure inside the plant cell and the plant cell stands stiff in an upright position.

Secretions of the pituitary gland are most directly regulated by the

Answers

The hypothalamus.

The hypothalamus is the link between the nervous system and the endocrine system. It synthesizes and secretes hypothalamic hormones. These hormones will either stimulate or inhibit the pituitary gland, which releases hormones that go throughout the body to the glands and organs.

Final answer:

The hypothalamus, a part of the brain, most directly regulates the secretions of the pituitary gland. It does this by producing releasing or inhibiting hormones that control the secretion of hormones from the anterior pituitary and by signaling the posterior pituitary to release hormones.

Explanation:

The pituitary gland, often called the hypophysis or "master gland", is located at the base of the brain. It is regulated most directly by the hypothalamus. The hypothalamus produces releasing or release-inhibiting hormones that control the secretion of hormones from the anterior pituitary. For example, the hypothalamus will produce regulatory hormones, which can be releasing hormones or inhibiting hormones, prompting more or less of the anterior pituitary hormones to be secreted. These travel from the hypothalamus through the hypophyseal portal system to the anterior pituitary where they exert their effect. The posterior lobe of the pituitary gland, in turn, receives signals via neurosecretory cells to release hormones produced by the hypothalamus.

The secretions of the pituitary gland are most directly regulated by the releasing or release-inhibiting hormones produced by the hypothalamus. The anterior portion of the pituitary gland is regulated by these hormones, while the posterior pituitary receives signals from the hypothalamus to release hormones. The pituitary gland, often referred to as the "master gland", produces and secretes nine different peptide or protein hormones.

A researcher recorded eight different species of bumble bees in the grasslands of Arkansas. Each species is present in large numbers. Which reason most likely explains the diversity of bumble bees in the grasslands ?

Answers

Bumblebees are the pollinators that are declining in numbers due to destruction of grasslands. Bumblebees require flowering plants for their growth and multiplication as these suck nectar from the flowers. The nectar is used to make honey that acts as food for the bumblebee colony. They also make their nests in the flower-rich grasslands. Thus, grasslands act as habitat for the bumblebees and this is the reason why they are found in abundance in the grasslands.
Final answer:

The diversity of bumble bees in the grasslands of Arkansas is likely explained by the presence of different floral resources, suitable nesting sites, and the absence of major limiting factors.

Explanation:

The diversity of bumble bees in the grasslands of Arkansas is likely explained by several factors. One possible reason is the presence of different floral resources in the grasslands. Bumble bees rely on flowers for food, and different species of bumble bees may have different preferences for specific types of flowers. The presence of a variety of floral resources can attract and support a diverse community of bumble bees.

Another factor that may contribute to the diversity of bumble bees in the grasslands is the presence of suitable nesting sites. Bumble bees require suitable locations to build their nests and raise their young. The grasslands may provide a range of nesting opportunities, such as underground burrows or abandoned rodent nests, which can support multiple species of bumble bees.

Lastly, the absence of major factors limiting bumble bee populations, such as pesticide use or habitat destruction, may also contribute to the high diversity of bumble bees in the grasslands. When bumble bees are not threatened by these negative influences, they have the opportunity to establish and maintain diverse populations.

You are interested in purchasing a home. you can afford $1200 a month as a mortgage payment. how much can you pay for a home assuming a 30 year (360 months) loan at 4.25% interest? (please reference the loan information in the "task 2 data" cells as the arguments for your function.)

Answers

Final answer:

To determine how much you can afford for a home with a monthly mortgage payment of $1200, a 30-year loan, and 4.25% interest, you rearrange the mortgage payment formula to solve for the loan amount. After substituting the known values into the formula, we find that you can afford a home priced up to approximately $236,319.

Explanation:

To calculate how much money you can pay for a home, you should use the mortgage payment formula, which is M = P [r (1 + r) ^n] / [(1 + r) ^n – 1]. In this case, M is your monthly mortgage payment, P is the loan amount, r is your monthly interest rate (yearly interest divided by 100 and then divided by 12), and n is your number of payments (years of loan times 12).

In your situation, M = $1200, r = 4.25% / 100 / 12 = 0.00354 approximately, and n = 30 * 12 = 360. We can rearrange the formula to solve for P: P = M [(1 + r) ^n – 1] / [r (1 + r) ^n], substitute the values into the formula, and get P = $236,319 approximately.

Air moves into the lungs when the air pressure in the lungs is than the air pressure outside of the lungs this occurs when the muslces of the diaphragm

Answers

Air moves into the lungs when the air pressure in the lungs is lower than the air pressure outside of the lungs. This occurs when the muscels of the diaphragm contract.

You can see this by breathing in and out deeply. When you breath in you can feel your chest being pushed up and out by your diaphragm. The reason the pressure in the chest is lower is that when you breathe in you are increasing the volume of your chest. As there is the same amount of air in your chest the pressure decreases.

Make a concept map that shows how photosynthesis and cellular respiration are related

Answers

In plants, photosynthesis, occurring in chloroplasts, is an anabolic (bond-building) process whereby CO2 and H2O combine with the use of light (photon) energy. This yields O2 and sugar (i.e. glucose). This occurs in 2 phases: light-dependent and dark (Calvin cycle) reactions, which both continually recycle ADP/ATP and NADP/NADPH.
The catabolic (bond-breaking) process in plants is cellular respiration, in which glucose is broken down with O2 by glycolysis (cytoplasm only) and mitochondrial reactions (Krebs cycle and E.T.C.) to yield CO2 and H2O. These reactions recycle ADP/ATP and NAD/NADH. The CO2 and water produced by cellular respiration feed into the photosynthetic processes, and in turn, the O2 and glucose resulting from photosynthesis supply the respiratory reactions.
