In simple terms, Bacteria can be stated a large group of single-cell microorganisms and they can easily found everywhere which lack nucleus and organelles

Explanation:

From single cell of bacteria the number becomes, 2, 8, 64, ... and so on.

Explanation:

Bacteria is one of the best examples that show exponential growth.

The equation that shows the exponential growth of bacteria is

N = N₀ X 2ⁿ

If we consider the growth of the bacteria starts from 1 cell then,

N = 1 X 2⁰

N= 1

In 1 hour, the cell number becomes,

N = 1 X 2¹

N = 2

In 2nd hour, the cell number becomes,

N = 2 X 2²

N = 8

In 3rd hour, the cell number becomes,

N = 8 X 2³

N = 64

The growth continues exponentially and then becomes stationary after a certain period of time when enough nutrients are not present.

Thus from single cell of bacteria the number becomes, 2, 8, 64, ... and so on.

If modern animal fossils were ever found in a very ancient geologic period, it would have changed the whole evolutionary theories.

Option B.

Evolution as an event, is very slow and gradually progressive movement. It took millions of years for the unicellular bacteria to evolve and finally make the modern day humans. But the process isn't a haphazard and the evolution processes are well understood by humans. A scientist can clarify how the cell systems became complex to eukaryotic cells, the tissues began to develop, and then the organs and the organ system. The systems like circulatory system, nervous system, muscles, everything slowly grew to evolve animals into a superior one. This is the theory in present days and this is supported by Fossils and different other proofs.

But if one day, a fossil is found which is actually the fossil of a modern animal in very ancient time, its not collaborative with the theories. Modern day animals are born as a result of huge evolutions and presence of them in very ancient times is impossible. So this finding can wipe out present day theories of evolution.

Estrogens, progesterone, and human Chorionic Gonadotropin (hCG) are the main hormones that influence the uterus during pregnancy. First released by the corpus luteum, these hormones stimulate changes that nourish the embryo and maintain the pregnancy. As the gestation advances, the placenta takes over the secretion of these hormones, which continue to play vital roles in the healthy progression of pregnancy.

The hormones that most directly influence the uterus during pregnancy are primarily estrogens, progesterone, and human Chorionic Gonadotropin (hCG). These hormones are firstly secreted by the corpus luteum during the initial weeks of pregnancy, resulting in the generation of decidual cells that nourish the early stage embryo, or blastocyst, before the placenta forms.

As the gestation progresses, the placenta becomes the primary endocrine organ, taking over the role of hormone secretion from the degenerating corpus luteum. Estrogen, progesterone, and hCG secreted by the placenta are responsible for most of the changes experienced during pregnancy.

For instance, estrogen mainly maintains the pregnancy and promotes fetal viability while also stimulating tissue growth in both the mother and fetus. Progesterone, on the other hand, prevents new ovarian follicles from developing and suppresses uterine contractions, protecting the developing fetus.

Lastly, hCG promotes the survival of the corpus luteum, stimulates the male fetal gonads to secrete testosterone necessary for the development of the male reproductive system, and ensures the placenta continues to secrete progesterone crucial to maintaining the pregnancy.

polar covalent bonds

Explanation:

In a water molecule, two hydrogen atoms are bonded to a single oxygen atom by covalent bonds, where they share pairs of electrons for stable electron configuration.

In a single molecule of water, two hydrogen atoms are bonded to a single oxygen atom by covalent bonds. This type of bond forms when two atoms share pairs of electrons. In the case of water, each hydrogen atom forms a covalent bond with the oxygen atom, leading to their stable bonding structure within the molecule. This sharing of electrons allows all atoms in the water molecule to have a stable electron configuration.

Humans are more closely related to hogs than hogs are to guinea pigs.

Explanation:

The difference in the amino acid sequence of a protein is used to know the  relation between organism i.e. how closely they are related.

It is known that proteins are the result of DNA sequence ie genes of the organism.

The gene or protein is compared between organisms to understand the evolutionary evidence and similarities between them.

The less is the difference the more is the two organisms closely related as in the case of hog and human which have only 1 amino acid difference in their insulin enzyme. While guinea pig is having  a difference of 17 amino acids so it is expected to be distantly related.

These relations helps the scientist to resolve the issues of crisis say insulin. They zero out the possibility of extracting the enzyme genes of possible organism and increase the yield.

Answer:

c

Explanation:

Answer:

B

Explanation: For example lions and cheetahs need similar resources so they compete with each other.

The the word competition mean in biology is C. Organisms from the same species looking for the same resource**.

Competition in biology is the interaction between organisms that are competing for the same limited resources. These resources could be food, water, space, or mates. Competition can occur between organisms of the same species or between organisms of different species.

When competition occurs between organisms of the same species, it is called **intraspecific competition**. Intraspecific competition can be very intense, as the organisms are very similar and have the same needs. For example, two male lions competing for the same female lion are engaging in intraspecific competition.

Competition is an important part of the natural world. It helps to regulate populations and ensures that the strongest and most adaptable organisms survive.

The end of life for a group of organisms or a species is known as extinction. This usually happens due to changes in environmental conditions or during a mass extinction event. An example of mass extinction is the 'great dying' at the end of the Cretaceous period, which marked the end of the dinosaur age.

The end of life for a group of organisms, usually a species, is referred to as extinction. Extinction is a natural part of macroevolution, indicating evolutionary changes above the species level. There are numerous causes of extinction, which often involve alterations in environmental conditions or mass extinction events.

A mass extinction event refers to a sudden, drastic reduction in biodiversity brought about by an extraordinary environmental condition that wipes out the majority of species within a relatively short geological time period. Great examples of mass extinction are the end of the Cretaceous period, often known as the 'great dying', which marked the end of the dinosaur age, and the current high rate of extinction, considered 500-1000 times the normal rate, largely caused by human activities.
