what is biological classification? explain it
Answer:
Biological classification is the process by which scientists group living organisms. Organisms are classified based on how similar they are. Historically, similarity was determined by examining the physical characteristics of an organism but modern classification uses a variety of techniques including genetic analysis.

Explanation:
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?
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.

You observe the growth of a group of plants that have been tipped over.
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.
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.

Explain the mechanism of water movement from the roots up the tree to the leaves
1-Water is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. 3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.

What happens during G1 phase?
Answer:
please mark me brainliest
Explanation:
G1 phase. G1 is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. During this time, the cell grows in preparation for DNA replication, and certain intracellular components, such as the centrosomes undergo replication.

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 does the liver help in maintaining homeostasis
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.
Explain mutations and how they can cause genetic disease
Identify the following observation as qualitative or quantitative
The solution turned blue in color
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.

O autocrine signaling
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.Learn more in:
