The most highly sensitive time within the developing embryo for the risk of malformation related to environmental teratogens is cleft palate at 8 weeks gestation. It is an opening in the roof of the mouth.

A teratogen is any substance and/or physical agent that may cause an irreversible abnormality in the structure of the developing embryo or fetus (e.g., classical pesticides such as DDT).

Cleft palate is a malformation mainly caused by mutagenic agents (teratogens) during pregnancy, which affects approximately one (1) of 650 births.

A cleft palate is a malformation that occurs when the two plates of the skull that form the roof of the mouth cannot be completely joined.

Answer:

Bone marrow is soft, spongy tissue at the center of bones, and it plays an essential role in creating RBCs. The marrow produces stem cells, which develop into RBCs, white blood cells, and platelets.

Answer:

its important for gametes to be haploid so when fusion of the Male and female gametes take place after fertilization the correct amount of chromosome numbers specific to the species can be restored

It is important for gametes to be haploid as just to maintain the chromosomal number. It is present for the sake of incorporation of both of the sets of chromosome in the progeny.

It is having 23 pairs of chromosomes that is having total of 46 chromosomes.

Because meiosis just  creates cells which are destined to be  the gametes  and in this reduction in the  chromosome number is just  critical that is  without the process, the union of the  two gametes  that are during  the fertilization that will result in  the offspring with just  twice of normal number of the  chromosomes.

Haploid cells in the  humans are just produced out  by meiosis. This is type of  the cell division in which the  single diploid parent cell  just divides to just  produce four with the non-identical  type of the haploid daughter cells. In  meiosis is just  used to get the type of the  produced  type of gametes and is are a  necessary kind of  precursor to  the sexual reproduction.

According to BBC, Human activities such as harvesting plants and hunting animals can unbalance the flows and cycles within those [SMALL SCALE ECOSYSTEMS ]ecosystems. Tree-felling may lead to soil erosion and a loss of habitat. Lack of shade and moisture in the soil can result in desertification.

According to National Geographic, Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

The key feature here is that individuals cannot evolve. Individuals are either adapted in their movement. This is how evolution by means of natural selection occurs.

The statements which can be formed using the given terminology are: Individuals have different genetics, leading to the evolution of populations. Individuals with adaptations are based on genetics, allowing for populations to undergo evolution. Thus, the correct options are C and E.

Evolution can be referred to as the change in heritable characteristics of biological populations over the period of successive generations. These characteristics are the expressions of genes, which are passed on from the parents to their offspring during the process of reproduction.

The statements which can be formed using the given terminology include: 1. Individuals have different genetics, leading to the evolution of populations. 2. Individuals with adaptations are based on genetics, allowing for populations to undergo evolution

The differences in health and mortality by gender is a phenomenon for which researchers have many possible explanations.

There have been studies that have indicated that there is enough variation in the average health of males and females to conclude that there are factors at play that are affecting health.

Amongst the many possibilities, scientists have mentioned:
