Answer:
Answer is B. Ensuring early and adequate prenatal care.
Explanation:
Prenatal care can be described as the care, such as information and medical care , given to pregnant women during pregnancy , before delivery.
This is very important , because it prevents complications during pregnancy, which can lead to maternal mortality, and support the birth of healthy children.
Infant mortality is the death of the child at birth or shortly after, while maternal mortality is the death of pregnant women during pregnancy or shortly after delivery.
Therefore, ensuring early and adequate prenatal care is the best factor that must be put in place to address the issue of maternal mortality and infant mortality rate.

Answer:
Four daughter cells are produced each with 40 chromosomes. The daughter cells would exhibit genetic variations and would not be genetically identical to each other.
Explanation:
Meiosis is a cell division that forms four daughter cells from one parent cell as two sequential division meiosis I and meiosis II do not include any DNA replication between them. Crossing over during prophase-I of meiosis-I includes the exchange of genetic segments and occurs between the homologous chromosomes. It produces new gene combinations in the daughter cells which were otherwise not present in the parent cell.
Since there is no DNA replication between meiosis I and meiosis II, the daughter cells have half the number of the chromosomes compared to the parent cell. This occurs as homologous chromosomes move towards the opposite pole during anaphase I.
Therefore, a parent cell with 80 chromosomes will make a total of 4 daughter cells by meiosis. Each daughter cell would have 40 chromosomes. These daughter cells would have some new gene combinations and would be genetically dissimilar among themselves.
The independent variable is the one that causes an effect on the dependent variable. In this case, the independent variable is <u>depth.</u> Different depths lead to a variation in temperature. 2)<em> depths</em>.
<h3>What are de dependent and independent variables?</h3>
- Independent variables are those modified or changed by the researcher to study how this change affects another variable and hence the results.
This variable is not affected by any other one but influences or causes a reaction in other variables.
- The dependent variable is the one influenced by the independent variable, and is affected by any change on this last one.
Its response might be either directly proportional or inversely proportional to the change in the independent variable.
Now let us answer the question.
The aim of the study was probably to analyze how temperature changed with depth.
So, according to this, depth influenced on the temperatureof water.
- The independent influencing variable is <u>depth</u>.
- The <u>dependent affected variable</u> is water temperature.
The correct option is 2. depths.
