Compare and contrast aerobic respiration with photosynthesis in

Biology

1 answer:

Nataliya [291]4 years ago

5 0

Answer:

Aerobic respiration;this is the process of breaking down of glucose with Oxygen to generate energy as ATPs in living cells

Location- Matrix and inner membranes of mitochondria

Energy source_oxidative phosphorylation of glucose

Waste product-water( oxygen accept the final electron to form water)

38 ATPs from 1 glucose molecule

Explanation:

Photosynthesis; this is the process of reducing C02 with hydrogen ion, from water in the presence of sunlight , enzymes and green pigment chlorophyll to form glucose

Location- stroma and thylakoid membranes of chloroplast

Energy source-photo-phosphorylation(sunlight)

Waste product-Oxygen

18ATPs

The first insects to be attracted to a corpse are the _____. blowfly maggots blowfly larvae blowfly pupae blowfly adults looking

Alla [95]

Answer:

Blowfly adults looking for a place to lay their eggs

Explanation:

Blowfly adults are attracted to the gases and fluids of a dead body and usually lay their eggs on a dead body within the first two days after death.

The eggs then turn into larvae then enter pupal stages and then become adults themselves. Forensic entomologists can determine how long a body has been dead by the stage of development of the blowfly with the ambient temperatures that have been present.

What did Miescher contribute to the discovery of DNA? When was this discovery made?

NikAS [45]

Answer:

Explanation:

In 1869, Friedrich Miescher isolated "nuclein," DNA with associated proteins, from cell nuclei. He was the first to identify DNA as a distinct molecule. Phoebus Levene was an organic chemist in the early 1900's. He is perhaps best known for his incorrect tetranucleotide hypothesis of DNA.

Q - Describe the Mitoses with the help of diagram. write its different phares and explain them.

bonufazy [111]

Answer:

Mitosis is a type of cell division in which single haploid cell (n) or diploid cell (2n) divides into two haploid or diploid daughter cells that are same as the parent.

Mitosis occurs in somatic cells of plants and animals. In this cell division, the two daughter cells have the same number of chromosomes as that in the parent cells.

Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase.

1.Prophase:-

It is the first visible stage in karyokinesis. The chromosomes appear as long coiled threads called chromatids. The chromatin becomes shorter, thicker and visible due to the condensation of DNA. The chromatins are now called chromosomes. Stainability of nucleus increase. Each chromosome starts to splits longitudinally into two sister chromatids. These sister chromatids are attached to each other at the centromere. The nuclear membrane and nucleolus start to disappear and by the end, it will be completely disappeared.

ii. Metaphase:-

Nuclear membrane and nucleolus completely disappears and simultaneously appearance of spindle fibers. Spindle fibers are attached to the centromere of a chromosome. The chromosomes are arranged on the equatorial plane. The process of gathering of chromosomes in equator is called congressional and plate formed is called metaphasic plate.

iii. Anaphase:-

The centromere of each chromosome splits into two sister chromatids and forms two daughter chromosomes. The daughter chromosomes are pulled towards the poles due to the contraction of spindle fibres and stretching of interzonal fibers. During polar movement, the chromosomes show different shapes i.e. J, U, V, L or I shaped in appearance. At the end of anaphase, each pole will get one set of daughter chromosomes. It is the shortest phase and is also known as a migratory phase.

iv. Telophase:- The daughter chromosomes reach respective poles and uncoil and become thin, long and visible. The spindle fibres start disappearing and finally disappear. The nuclear membrane and the nucleolus reappear.

Two nuclei are formed at the end of telophase. Both the nuclei have the same number of chromosome as the parent cell. It is the last visible stage of karyokinetic and is also known as reorganization phase.

It is followed by cytokines or division of cytoplasm.

Flowering plants and shrubs are unable to grow in deciduous temperate rain forests. What is the possible reason for this phenome

Dima020 [189]

The purpose for this wonder is on account of deciduous backwoods are situated close to the north segment of the earth subsequently, have a colder atmosphere that dazes plants from developing at a hoarding rate. Additionally, the daylight is uncommon in this condition which could enormously influence the organic development of these sorts of plants.
