Answer:

Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell's function is determined, in part, by its shape.

Transpiration is the evaporation of water at the surfaces of the spongy mesophyll cells in leaves, followed by loss of water vapour through the stomata . Transpiration produces a tension or 'pull' on the water in the xylem vessels by the leaves. Water molecules are cohesive so water is pulled up through the plant.

Transpiration is the outcome of the association between the xylem vessels and stomata present in the leaves.  

• The evaporation of water at the surfaces of the spongy mesophyll cells in the leaves succeeded by the loss of water vapor via the stomata is termed transpiration.  

• Transpiration generates a pull or tension on the water in the xylem vessels, and these molecules of water are cohesive so pulling up of water takes place through the plant.  

• The primary sites of transpiration are the stomates present in the leaves. This stomata comprises two guard cells, which produce a small pore on the leaves' surfaces. These guard cells monitor the closing and opening of the stomates in reaction towards different environmental stimuli, and thus, regulate the loss of water by transpiration.

Explanation:

Hyposecretion of insulin is the production when number of hormone or too little of a hormone. It can be caused by the destruction of hormone-secreting cells, such as in Type 1 diabetes, or by a deficiency in a nutrient that is important for hormone synthesis. Hyposecretion can be treated with hormone-replaceme

Answer:

Why is there less energy at each trophic level?

Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. ... A food chain can usually sustain no more than six energy transfers before all the energy is used up.

Answer:

Photosynthesis takes place through several steps which occur during two stages: the light phase and the dark phase.

Explanation:

In the light-dependent process, which takes place in the grana, the stacked membrane structure within chloroplasts, the direct energy of light helps the plant to make molecules that carry energy for utilization in the dark phase of photosynthesis. The plant uses light energy to generate the co-enzyme Nicotinamide adenine dinucleotide phosphate, or NADPH and ATP, the molecules that carry energy. The chemical bonds in these compounds store the energy and are used during the dark phase

The dark phase, which takes place in the stroma and in the dark when the molecules that carry energy are present, is also known as the Calvin cycle or C3 cycle. The dark phase uses the ATP and NADPH generated in the light phase to make C-C covalent bonds of carbohydrates from carbon dioxide and water, with the chemical ribulose biphosphate or RuBP, a 5-C chemical capturing the carbon dioxide. Six molecules of carbon dioxide enter the cycle, which in turn produces one molecule of glucose or sugar.

Answer:

As a result of daily activities, man has been altering the environment since before recorded history. Increased urbanization, the Industrial Revolution, and an overall larger population base have accelerated the process considerably. While providing numerous societal benefits, modern chemical technology has also brought about a marked increase in the number and variety of chemicals ultimately entering natural surface waters. The last century has witnessed a substantial growth of the chemical industry and it is estimated that there are presently over two million known, chemical compounds in existence, with nearly 250,000 new compounds currently synthesized each year. Of this number, it is estimated that approximately 1,000 new chemicals each year will find their way into the environment as the end result of marketing, use, and disposal.

By means of hydrogen bonds, the nucleic acid thymine bonds with adenine in a section of double-stranded DNA.

Nucleic acids are the monomer units of DNA which is composed of long chains of nucleic acids linked together by phosphodiester bonds as well as by hydrogen binds between two DNA strands.

In double-stranded DNA molecule, the nucleic acid adenine bonds with thymine, while guanine bonds to cytosine through hydrogen bonds.

Therefore, thymine bonds with adenine in a section of double-stranded DNA.

Organic Matter: Carbon (C) is what makes something organic; if it doesn't contain carbon, then it is not a living thing. For this reason, carbon is often considered the element of life.

Photosynthesis: Carbon is part of the compound Carbon Dioxide (CO2), and CO2 is a reactant in the process known as photosynthesis.

Cellular respiration: Although similar to photosynthesis, cellular respiration contains CO2 as a product, not a reactant, as is the case with photosynthesis.

Answer: the ploidy of the zygote would be genetically identical to the parent cells. since mitosis doesn't reduce the number of chromosomes by half, each successive generation would have twice as many chromosomes as the last.

Explanation:

The ploidy of any zygote formed from egg/sperm produced by mitosis rather than meiosis would be tetraploidy.

Meiosis reduces the diploid chromosome (2N) in parent cells to haploid (n) in the daughter cells. During fertilization two haploid cells (sperm and egg) fuse to form a 2n zygote.

If mitosis replaces meiosis for the production of eggs/sperms, it means eggs and sperms would have complete diploid chromosomes instead of haploid. Thus, during fertilization 2n sperm fuses with 2n egg to form a 4n zygote. A 4n individual is known as a tetraploid.

If mitosis remains as the division for producing eggs and sperms, it means the ploidy level of each successive generation will be doubling from 4n to 8n to 16n, on and on.

Answer:

The time of day the second time the student measured the length of the fence shadow was either earlier or later than the first time she measured the shadow.

Explanation:

As the first time the student measured the shadow of the fence gave an answer of 2 meters, the second time gave an answer of 3 meters. For this reason, the shadow is longer in length. This means that the sun is closer to the horizon, yielding a light beam that is closer to the ground.

Moreover, if the sun was directly above the fence post, there would be no shadow. However, because the sun is closer to the horizon, showing that it is earlier or later then the first measurement, the second measurement has a longer shadow.
