Answer:

The Option A is correct i.e.

Sexual organisms increases genetic diversity for changing environments

Explanation:

Reproduction is the biological process by which new organisms are produced from their parents.

In asexual reproduction, an organism can reproduce without the involvement of another organism. By asexual reproduction, an organism creates a genetically similar or identical copy of itself.

Sexual reproduction typically requires the sexual interaction of two specialized organisms, called gametes, which contain half the number of chromosomes of normal cells and are created by meiosis, with typically a male fertilizing a female of the same species to create a fertilized zygote. This produces offspring organisms whose genetic characteristics are derived from those of the two parental organisms.

The diversity in genetics makes it possible for the offspring to cope with changing environmental conditions. Because, the offspring are diverse in constitution, some offspring will always be able to survive harsh environmental conditions due to their genetic make up.

Answer:

The correct option is A.

Explanation:

There are two basic types of reproduction, they are asexual and sexual reproduction. Asexual reproduction involves the division of a mature organism into two different organisms through binary fission or other forms of asexual reproduction. In this case the offspring is similar both physically and genetically to the parent organism. There is no genetic diversity in this case and the same disease can easily wipe out the entire population of the organism.

Sexual reproduction on the other hand requires two different organisms. During the reproductive process the genetic materials from the two organisms get mixed up thoroughly, so they end up giving birth to offspring that are quite different from them genetically.

The diversity in genetics makes it possible for the offspring to cope with changing environmental conditions. Because, the offspring are diverse in constitution, some offspring will always be able to survive harsh environmental conditions due to their genetic make up.

Human embryonic development is the development and formation of the human embryo. It is characterized by the process of cell div

iragen [17]

The statements that correctly describe gestation are: the normal period of gestation is about 40 weeks; the stages of this process include: zygote, blastocyst, embryo, and fetus; and changes to the form of the embryo come from differentiation and growth.

The gestation period in humans lasts about 40 weeks and comprises different stages and processes from conception until birth. The main stages of this process include:

Zygote: Fertilized ovum.
Blastocyst: Cluster of cells that is the result of the zygote going through cell division.
Embryo: Unborn human that is still developing, usually before the 8th week of gestation.
Fetus: Unborn human in development after the 8th week of gestation.

Moreover, this process implies differentiation as cells specialize for specific functions, for example, muscle cells or nerve cells, and growth as the number of cells increases and therefore the embryo or fetus increases in size.

Ok, no boxes but whatever

Mammals - Endothermic Homeostasis (Warm Blooded), Hairy Body, Have babies live

Birds - Endothermic Homeostasis(Warm Blooded), Have eggs, feathers, claws

Bacteria - Single celled, use binary fission to divide

Fungi - Multi or single celled, have chitin cellular walls

Plants - Have cellulose plant walls, multicellular organism

Archae Bacteria - Same as normal, except they live in crazy enviorments, like at the bottom of the ocean or in a volcano or radiation pool

Protozoa - Single celled organism class, like ameoba

Ocean currents occur<br> because water has different<br> amounts of salt.<br> True of False ?

harkovskaia [24]

Answer:

False

Explanation:

Ocean currents are driven by wind, water density differences, and tides. Oceanic currents describe the movement of water from one location to another. Currents are generally measured in meters per second or in knots (1 knot = 1.85 kilometers per hour or 1.15 miles per hour).
