During which phases of the cell cycle are chromosomes composed of two chromatids?
Answer:
The correct phases are S phase, prophase, anaphase.
Explanation:
The cell cycle, the sequence of events spanning the period from the completion of one cell division to the end of the next division, involves both the division of the cell nucleus (karyokinesis) and the division of the cytoplasm (cytokinesis). S phase, the next section of the interface, is marked by a dramatic increase in DNA synthesis and the synthesis of histones which are major cellular proteins bound to DNA. The cell is preparing for the start of mitosis. Chromosomes duplicate lengthwise, and each chromosome consists of two identical "chromatids."During prophase, the degree of packing of the chromatin increases, so the chromosomes become shorter and thicker and the centromeres begin to become visible. Each of the chromosomes, due to its duplication in S phase, is made up of two identical chromatids, called sister chromatids. Anaphase is the short phase, the sister chromatids begin to separate and migrate to the poles. Once the two chromatids separate, each is called a chromosome.

2. Explain how similar and different sexual reproduction in plants and animals is?
Answer:Both plants and animals reproduce sexually, producing a male and female gamete, which fuse to form a zygote. However, plants are also able to reproduce asexually, unlike most animals. ... In sexual reproduction in animals, the two gametes are the spermatozoa and the oocyte, which when fused become the ovum.

Explain how mRNA is formed from the DNA template.
Answer:
mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.

Answer:
★ People's awareness of the environmental changes brought about by industrialization
Explanation:
Hope you have a great day :)
Industrial Revolution was the phenomenon that led to the application of ethical standards to relationships between people and their environment.
Environmental ethics is a current philosophical thought that originated after the Industrial Revolution as a result of the environmental damage that had been done to different ecosystems and species as a result of the industrial revolution.
Environmental ethics proposes a modification in the relationships between human beings and their environment from a moral perspective to ensure the preservation or restoration of said natural values.

Answer: Phylum is at level 2.
All living organisms are classified, and the reasons for this are so that they can be examined better, to know and discover their relations, their evolutionary paths etc. while in the past there have been some more simplified classifications, the modern one is complex and well established, based on the characteristics of the organisms(living and died out).

When resources are stable over a long period of time, a species' population can be expected to
O die out.
o increase.
O stay the same.
O decrease.
In an environment with stable availability of resources, the population can still grow because there are enough resources for this population to survive. Option B. The species' population can be expected to increase.
This question is related to growth models.
Logistic growthA growing population that inhabits a limited space is gradually affected by density, rebounding in the multiplication rate.
The population growth per capita rate decreases as population size increases.
The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
Carrying capacityCarrying capacity refers to the maximum point at which the environment can support a growing population.
K is a constant. It coincides with the population size when natality rate and mortality rate are equal to each other. This is the equilibrium point.
• If the population size, N, is inferior to K (N<K), the population can still grow.
• When N approximates to K, the population´s growth speed decreases.
• When N=K, the population reaches equilibrium,
• When N is superior to K (N>K), the population must decrease in size because there are not enough resources to maintain that size.
So when the population size exceeds K, carrying capacity makes the population decrease in size.
But if there is a constant availability of resources, the population can still grow because there are enough resources for this population to survive. In this situation, N<K.
When resources are stable over a long period of time, a species' population can be expected to INCREASE. Option B.

What do you know about Restriction Enzymes?
Why do we use Restriction Enzymes?
When do we use Restriction Enzymes?
How can we edit bacterial genome?
Help!
Answer:
Explanation:
Restriction enzymes refer to enzymes that is produced by a bacteria which has the ability to cleaves DNA property to a specific restriction sequence site within the molecule.
Restriction enzyme is use to cut DNA into smaller fragments by preventing the replication of the phage DNA .
Restriction enzyme is use when there is infection or foreign materials that intrude into a bacterium,the bacterium uses it to defend itself against infections that might be cause by viruses, pathogens e.t.c.
Bacteria genome can be edited using CRISPR method. It is done with recombineering, which is a technique that uses phage recombination method to enhance homologous recombination of DNA fragments.
choose the correct statement about the earth crust A. the earth crust is thin and could be compared to an eggshell B. most of the earth crust is only 6 km deep C. the earth crust is around 200 km deep D. the earth crust is the thickest layer
''A. the earth's crust is thin and could be compared to an eggshell'' is the correct answer.
Why earth's crust is considered an egg shell?The egg is considered a tiny model of the Earth. The thin shell of the egg represents the Earth's crust which is divided into plates. Both earth and egg have a thin and brittle shells. The crust of the earth is broken into various pieces like the cracked shell of a boiled egg. The mantle of the earth is like the egg white part whereas the core of the earth is present in the center like the egg yolk. The earth's crust is broken into pieces that geologists called it plates. The inside of the planet earth is layered like an egg. Scientists considered the surface of the Earth to be cracked like a big eggshell. They call these pieces tectonic plates that cover the Earth. The plates float slowly on the surface and sometimes crash with each other, and move away from each other.
So we can conclude that option A is the right answer about the earth's crust.

Which of the following undergo meiosis?
A Liver cells
B. Sperm cells
C. Unicellular organisms
D. All of the above
rion
таасан
Answer:
The sperm cells.
Explanation:
Liver cells, sperm cells and unicellular organisms all undergo meiosis. Therefore, the correct option is D.
A specific cell division known as meiosis occurs in sexually reproducing organisms. The cells produce gametes through this process, which are the specialized sex cells used in sexual reproduction. Despite not being directly involved in reproduction, liver cells can undergo meiosis. Under certain circumstances, meiosis in liver cells can be induced to form haploid cells.
Male gametes, or sperm cells, undergo meiosis as part of spermatogenesis. Haploid sperm cells with half the number of chromosomes than the parent cell are formed during meiosis in the testis. Depending on their reproductive strategies, unicellular organisms may also undergo meiosis to produce haploid cells that can mate with other haploid cells during sexual reproduction.
Therefore, the correct option is D.
