How will auxin influence cell growth in the roots of these plants?

Auxin will build up on the lower side of the root and inhibit cell growth.

Auxin will build up on the lower side of the root and stimulate cell growth.

Auxin will build up on the upper side of the root and inhibit cell growth.

Auxin will build up on the upper side of the root and stimulate cell growth.

Answers

auxins will build up on the lower side of the lower side of the root and inhibit cell growth.

Auxin is responsible for the growth of cells in the roots of plants. Auxin build up on the lower side of the root which inhibit the cell growth. Auxins have an inhibitory effect on primary root growth. Thus, the correct option is A.

What is Auxin?

Auxin is a plant growth hormone, which promotes cell growth and elongation of the plant. In cell elongation, auxin alters the plant wall plasticity making it easier for the plant to grow upwards. Auxin also influences the rooting in the plant.

Auxins have an impact on the growth of roots. Auxins facilitate the initiation of roots in plants. These hormones induce both growth of root branching (root initiation) and roots that are pre-existing. They also play important role in the formation of the adventitious root.

Therefore, the correct option is A.

In order to test the effects of a new drug, you isolate the messenger RNA molecules from both treated and untreated eukaryotic cells and separate them according to size using gel electrophoresis. In each lane of the gel, the shorter RNA molecules migrate more quickly through the gel and end up near the bottom of the gel while the longer RNAs migrate more slowly and remain near the top.


The samples that were loaded into each of the four lanes are as follows:

Lane 1: the primary RNA transcripts isolated from the nucleus of untreated cells
Lane 2: the primary RNA transcripts isolated from the nucleus of cells treated with the drug being tested
Lane 3: RNA isolated from the cytosol of untreated cells
Lane 4: RNA isolated from the cytosol of cells treated with the drug being tested

Which of the following conclusions is most likely to be CORRECT?

A. These results suggest that the drug affects RNA processing.
B. These results suggest that the drug digests DNA.
C. These results suggest that the drug inhibits DNA replication.
D. These results suggest that the drug contains a protease that targets this gene product.
E. These results suggest that the drug inhibits post-translational processing of this gene.

How is reproduction different than the other five characteristics of living cells?

Answers

Answer:

because reproduction is nature gifted and it is the way to increase population but living cells are the cells which keeps us alive

Reproduction differs from the other five characteristics of living cells because of the ability to replicate for continued existence.

The characteristics of living things include -MR NIGER D(acronym to remember)

Movement RespirationNutritionIrritabilityGrowthExcretionReproductionDeath

Now Reproduction differs from all the others because while others are processes that organisms need for existence or survival,Reproduction on the other hand is the reason for the continuation of existence of species(creation of a copy).  

Without reproduction,  Living organisms would go extinct and  would not be able to replicate themselves .

Identify the following observation as qualitative or quantitative
The solution turned blue in color

Answers

Hey there! I'm happy to help!

Quantitative data are data that have to with quantities (numbers).

For example, how many inches tall is the plant, what is the pH level of this fluid, what is the temperature of the meat, etc.

Qualitative data are data that can be described or that have a specific quality (qualitative).

For example, are the flowers yellow or green, is the fluid bubbling, does the meat smell burnt, etc.

We see that a solution turning blue doesn't have to do with numbers, so it is not quantitative. It is qualitative because it has to do with the quality (in this case, color) of the solution and not a numerical statistic.

Iron deficiency is one of the most common nutritional deficiencies in premenopausal women. Iron is a vital part of hemoglobin, which carries oxygen to red blood cells. Why do you think premenopausal women need more iron than men of the same age?

Answers

When a woman is entering her premenopausal state, fewer eggs are there for the ovaries to keep stimulating, so there is a high loss of iron in her menstrual blood.

So, a woman needs more iron than a man of the same age, because she is more prone to iron deficiency due to her loss of blood.

Answer:Premenopausal women shed blood as part of menstruation every month, which lowers the level of iron in the body. So, they need more iron than men and are also at a greater risk for this nutritional deficiency.

Why does the pectoral girdle need to be flexible while the pelvic girdle needs to be rigid?

Answers

Answer:

Flexibility: pectoral girdle is more flexible-less ligaments, ball and socket joint is shallower

Security: pelvic girdle is more secure, deeper socket. there are more dislocated shoulders than dislocated hips

ability to bear weight: pelvic girdle can bear more weight-the pelvic girdle has bones that are fused (os coxa) and a joint with the sacrum. the pectoral girdle has a little bone called the clavicle connecting it to the body wall.

Explanation:

The pelvic gridle is rigid to protect internal organs and support body weight whereas pectoral gridle require to provide movement to upper limbs.

The girdles are part of the appendicular skeleton which is attached to upper limbs and lower limbs, The upper limbs attach to pectoral gridles and lower limbs attached to pelvic gridles.

1. The pectoral gridle:

connects your upper limbs to the bones along the axis of your body.The pectoral girdle has two bones clavicle, or collarbone and scapula, or shoulder blade.it has ball and socket joint that provide movement to the upper limb.

2. The pelvic gridle:

made up of left and right coxal bones and sacrumattached to legs or lower limbs therefore, called hipbonessupports body weight and protect internal organsit is rigid needed to support the weight of the body.

Thus, the correct answer is - The pelvic gridle is rigid to protect internal organs and support body weight whereas pectoral gridle require to provide movement to upper limbs.

how does the liver help in maintaining homeostasis

Answers

Answer:

The liver plays a major role in blood glucose homeostasis by maintaining a balance between the uptake and storage of glucose via glycogenolysis and gluconeogenesis. The liver is the primary organ for glucose metabolism.

Glycogenolysis: Glycogenolysis is the biochemical pathway in which glycogen breaks down into glucose-1-phosphate and glycogen.  

Gluconeogenesis: Gluconeogenesis is the synthesis of glucose from non-sugar precursors, such as lactate, pyruvate, and the carbon skeleton of glucogenic amino acids.

Answers

A cell sends messages to itself via Autocrine Signaling

Autocrine signaling refers to the generation and extracellular secretion of a given chemical messenger that interacts with receptors present in the plasma membrane of the same target cell, thereby initiating a signal transduction pathway.

An example of an autocrine signaling pathway is the production and secretion of the cytokine interleukin-1 (IL-1) pro-inflammatory cytokine in monocytes.

Moreover, paracrine signaling is a type of signaling that occurs between local cells.

Endocrine signaling is a type of signaling pathway that occurs between distant cells. This type of signaling is mediated by chemical messengers called 'hormones' which are released from endocrine cells and travel throughout the body.
