Answer:
A. The heartbeat can be heard
Explanation:
After the first trimester, during the fourth month, the heartbeat of the fetus becomes loud enough to be heard with the help of a stethoscope placed on the abdomen of the mother.
From fifth to the seventh month of the development, kicks and jabs are felt by the mother as the fetal legs grow and develops. Languo, a wrinkled pink colored skin covers the fetus.
Languo is in turn covered with a white greasy substance called vernix caseosa.
From eighth to ninth months, rotation of the fetus places its head pointing towards the cervix to facilitate childbirth later.
The development of testes takes place in the seventh month while the body hairs become disappeared in the eighth month.
is a functional unit that results from interactions of abiotic, biotic, and anthropogenic components and are a combination of interacting, interrelating parts that form a unitary whole. Ecosystems vary in size. They can be as small as a puddle, or as large as the earth itself. Basically, any living and non-living things interacting together can be considered an ecosystem. Within each ecosystem, there are habitats that vary in size. A habitat is a place where a population lives. A population is a group of living organisms of the same kind living in the same place at the same time. Natural ecosystems are made up of abiotic factors such as air, water, rocks, and energy and biotic factors such as plants, animals, and microorganisms.

Explanation:
If the pedigree you are referring to is the one that is attached then the answer would be:
A pedigree shows how a trait is passed on throughout generations. Like it says in the question, the squares represent males. If the square isn't shaded in, then that means they are unaffected by the trait or normal. If it is shaded, they are affected.
All you need to do for the first question is count the number of squares you see in the whole pedigree. In this case, there are 8.
The second one is asking how many are affected, or have hemophilia. You need to count the number of squares that are shaded in. In the pedigree, we see 3.
Answer:
The mRNA molecule will be synthesized running in the 5' to 3' direction.
Explanation:
From the DNA sequence:
5'-ATCGTACCGTTA-3'
3'-TAGCATGGCAAT-5'
mRNA sequence is
5'-AUCGUACCGUUA-3'
Amino acid sequence will thus be:
Ileu-val-pro-leu.
