Answer:

A zygote is a fertilized ovum. The germ cells undergo meiosis to reach a haploid state (n) as part of spermatogenesis and oogenesis. The sperm and the unfertilized ovum reinstates a chromosome set in zygote in a diploid state (2n).

After fusing with the sperm, the second stage of meiosis takes place for separation of chromatids. Post-fertilization, mitosis of the zygote is initiated which develops into a mature offspring exhibiting characteristics of its parent.

Explanation:

The zygote stage development occurs in the first week of fertilization. The genome of the zygote is the combination of DNA in each gamete and contains all the genetic information required to form an individual.

Answer:

The three processes from left to right are:

<u>Replication</u>   DNA  <u>Trancription</u>  RNA  <u>Translation</u> Protein

Explanation:

The process in question in the diagram is called the central dogma of life which describes the flow of genetic information from DNA to RNA to Protein. The three processes involved are:

  1. DNA Replication
  2. Transcription
  3. Translation

DNA Replication:

DNA replication is the process by which DNA makes a copy of itself. Replication of DNA is semi-conservative. this means that each new helix is a combination of an old (parent) strands and a new (daughter strand). The parental strand is used as a template to generate a complementary daughter strand.

Transcription:

Transcription is the formation of an RNA transcript of the DNA template. This process yields a mRNA that is further used as a code to manufacture proteins in the process of translation.

Translation:

Translation decodes the mRNA formed in transcription to generate proteins with specific amino acid sequence.

Answer: Anaerobic, Aerobic

Explanation: Aerobic means with Oxygen,while Anaerobic means without oxygen. Aerobic exercise like running,bike ride,walking increases blood flow. In Aerobic exercise with oxygen,your body produces the muscle need to perform a needed exercise. While in Anaerobic exercise without oxygen means oxygen demand is greater than oxygen supply.

kari74 [83]

Answer: Dominance of Gene for Bright Yellow Coloration.

Explanation: Gene carries the genetic makeup of a particular organism. It house all the information of all living organisms.

According to the phenomenon expressed by Gregor Mendel (law of Inheritance), genes are divided into two; dominant and recessive. The gene responsible for bright yellow color is more dominant in ascending generation of the frog which translates that gene responsible for green color is recessive.

Which of these is the study of interactions among organisms and their environment including its living and nonliving parts?
MakcuM [25]

<u><em>Ecology</em></u><em> is the study of interactions among organisms and their environment including its living and nonliving parts.</em>

Answer: A. Ecology

Explanation:

Ecology is the investigation of how living beings associate with each other and with their physical condition. The conveyance and bounty of living beings on Earth is moulded by both biotic, living-life form related, and abiotic, nonliving or physical, factors.

Ecology is learned at numerous levels, including creature, populace, network, biological system, and biosphere. Water accessibility is a case of an abiotic, or nonliving, factor that can influence dispersion of creatures.

Accessibility of supplements given by different life forms is a case of a biotic, living-creature related, factor that can impact appropriation.
