Mention the function of oveary ,ovduct and utterus in the female reproductive system. how essential materials are supplied for the development of foetus​?

Answers

Answer:

- The ovary is the female organ that produces the female gametes

- The oviducts are tubes that extend from the ovaries to the uterus  

- The uterus is an organ that acts to nourish and house a fertilized egg until the fetus is delivered  

- Materials are supplied by the mother's placenta  

Explanation:

The ovaries are the female gonads that function to produce and release female gametes (i.e., oocytes) into the reproductive tract. These organs are also in charge of producing female hormones (e.g. progesterone). The oviducts, also known as fallopian tubes, are a pair of tubes that extend from each ovary to the top of the uterus. The uterus is a thick muscular organ of the female reproductive system that nourishes and houses the embryo and fetus. Finally, materials such as oxygen and nutrients pass from the mother's bloodstream through the placenta which is connected to the fetus by the umbilical cord.

Different organs work together to create an ____________ that carries out a specific process in the body.
A. organ system

B. cell

C. tissue

Answers

Answer:

organ system A

Explanation:

Answer:the answer is a

Explanation:

The pH of a solution is a measure of how acidic or basic it is. The greater the pH, the more basic the solution is. Corals and other marine invertebrates require less energy to make their exoskeletons and shells when ocean water is slightly basic. As carbon dioxide concentrations in Earth’s atmosphere rise, ocean water absorbs carbon dioxide and becomes more acidic. This process is called ocean acidification. How do you think ocean acidification will affect the coral reef?

Answers

Explanation:

Because coral reefs have limestone (calcium carbonate), the coral reefs will be greatly affected. The increase in hydrogen ions in the ocean will corrode the coral reef, making it inhabitable for species. This will affect the crabs that get their food and the community that lives within in it. Making countless of species to loose their lives and their way if living.

b. commensalism-
c. parasitism -
d. predator/prey -
e. competition -

Answers

Answer:

mutualism -Both species benefit

commensalism- One species lives with, on, or in another species (the host). The host species neither benefits nor is harmed from the relationship. The species that lives on the host is benefited.

parasitism - One species (the parasite) lives with, on, or in a host species, at the expense of the host species. Unlike in predation, the host is not immediately killed by the parasite, though it may sicken and die over time.

predator/prey -One species (the predator) hunts and kills another species (the prey)

competition -The struggle among organisms for the same limited resources in an ecosystem

A freckled man marries a woman without freckles. They have four children, two with freckles, and two without freckles. What are the genotypes of all these people?

Answers

Answer:

The genotype of the father: Ff

The genotype of the mother: ff

The genotype of the two children without freckles: ff

The genotype of the two children with freckles: Ff

Explanation:

Freckles (F) are is dominant trait, so one dominant allele in the genotype of an individual will cause he/she to have freckles.  Since the father has freckles, but only two of his children has freckles; that means that he has a heterozygous genotype.  In the Punnett Square, the offsprings' genotypes are shown, as well as the parents'.

A freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.

What is the significance of the freckle trait?

There are both dominant and recessive traits that determine the person's quality, such as freckles, which are dominant over being freckleless. When the parents with freckles cross with the parents without freckles, they will produce half the freckles and half the freckleless. The parent with a freckle is heterozygous (Ff), so two types of gametes will be produced, such as F and f, and will form Ff and ff offspring when crossed with the freckleless parent (ff).

Hence, a freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.

Answer: Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans.

Explanation: Usually three levels of biodiversity are discussed—genetic, species, and ecosystem  diversity.

Genetic diversity is all the different genes contained in all individual

plants, animals, fungi, and microorganisms. It occurs within a species as

well as between species.

Species diversity is all the differences within and between populations

of species, as well as between different species.

Ecosystem diversity is all the different habitats, biological communities,

and ecological processes, as well as variation within individual ecosystems.
