When a population reaches carrying capacity.
What is Natural selection?
An evolutionary mechanism is natural selection. Environment-adapted organisms have a higher chance of surviving and dispersing the genes that contributed to their success. Over time, this mechanism leads to the evolution and divergence of species.
One way to explain the millions of species that have existed on Earth is through natural selection.
The idea of evolution by natural selection is credited to Charles Darwin (1809-1882) and Alfred Russel Wallace (1823-1913), who co-wrote a paper on it in 1858.
Therefore, When a population reaches carrying capacity.

Explanation:
a rapid change in temperature with depth is kn own as a.
Answer:
Thermocline.
Explanation:
An ocean is a body of salt water which covers approximately 70% of the Earth's surface. About 97% of the Earth's water is comprised of ocean and as such it is the most prominent and defined feature of the Earth. There are basically four (4) categories of an oceanic basin and these are;
1. The Pacific ocean.
2. The Artic ocean.
3. The Atlantic ocean.
4. The Indian ocean.
A rapid change in temperature with depth is known as thermocline.
Basically, it is considered to be a thin but distinctive water region in a large body of fluid that is thermally stratified such as an ocean, in which temperature changes rapidly with an increasing depth.
This ultimately implies that, the temperature of water decreases rapidly (drastically) as the depth of water increases.
P680 is said to be the strongest biological oxidizing agent. Given its function, why is this necessary
Answer:
The correct answer is - it obtains electrons from the oxygen atom in a water molecule, so it must have a stronger attraction for electrons than oxygen has
Explanation:
P680 known as which contains a reaction center in photosystem two, it is a very strong oxidizing agent that catalyzes the transfer of electrons from H2O to a bound quinone, with the production of O2.
To have a stronger attraction for electrons than oxygen has, P680 gets electrons from the O2 atom in a water molecule.

Humans:
To put it simply, a human starts as a fetus, then they are born..so that's a baby, then they hit 2 years old and are considered toddlers, once they turn 5-6, they start kindergarten, so we no longer refer to them as toddlers, they are children, when they hit 13 we call them pre-teens, once they hit 15-16 we call them teens, 21-25 they are young adults, 25 up until 50's they are adults, once they hit 50-60 they are seniors.
Explanation:
What is the portion of the cell cycle during which the chromosomes are invisible under the light microscope because they are not yet condensed
Answer:
Interphase
Explanation:
The portion of the cell cycle during which the chromosomes are invisible under the light microscope is the interphase.
Generally, there are 2 main phases of the cell cycle, namely;
1. The interphase
2. The m phase
The interphase is further subdivided into 3 phases:
G1 phase: which is characterized by the growth and development of the cell and also the synthesis of DNA precursors.S phase: characterized by the synthesis of DNA and duplication of the centrosome.G2 phase: characterized by the synthesis of proteins and further growth/development of the cellThe m phase represents the active division phase, also known as mitosis.
Immediately the cell leaves the interphase for the m phase, the genetic materials in the cell condense, thicken, and become visible under the microscope as chromosomes. This phase of mitosis is known as the prophase and the chromosomes remain visible through the rest of the mitotic phase (metaphase, anaphase) until the last phase, which is the telophase/cytokinesis.
At telophase/cytokinesis, the chromosomes condense back and the daughter cells produced enters the interphase for a repetition of the cycle.

Explain what causes lightning and thunder
Answer:
lightning and thunder is caused by the rapid expansion of the air surrounding the path of a lightning bolt. Since the lightning takes so little time to go from point A to point B, the heated air has no time to expand. The heated air is compressed, raising the air from 10 to 100 times the normal atmospheric pressure.
Explanation:
Question: Explain what causes lightning and thunder
Answer: Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. Lightning is extremely hot—a flash can heat the air around it to temperatures five times hotter than the sun's surface.

Answer:
Clusters of cocci (i.e., grape-like cocci)
Explanation:
Cocci (in singular coccus) are spherical-shaped bacteria, while bacilli and spirilli are rod-shaped and spiral-shaped bacteria, respectively (in general, bacteria can be divided into these three categories by shape). Staphylococcus aureus forms irregular clusters of cocci (i.e., grape-like cocci) when viewed through a microscope. Some Gram-positive cocci include, for example, Staphylococcus aureus and Streptococcus pneumoniae. These species are well known to be bacterial pathogens capable of infecting humans.
Explain how seismic waves are used to determine composition, thickness and density of the interior of the Earth (write 2-3 sentences)
Explanation:
Seismic waves are elastic waves that are able to propagate within the subsurface.
The travel - time to depth expressed in form of velocity is used to determine the composition, thickness and density of the interior of the earth.
Different earth materials shows different behavior in response of seismic waves. By checking the attributes of the waves as they go through the subsurface, we can predict some of the properties of the underlying beds.In most cases, adaptive immune responses rely on the initial activation of _____ in secondary lymphoid tissue:
Answer:
This question lacks options, options are: a. macrophages
b. T cells
c. B cells
d. dendritic cells
e. epithelium
The correct answer is c.
Explanation:
In the secondary lymphoid organs is where foreign substances or antigens are presented and the specific immune response begins. They are the lymph nodes, spleen, and MALT. The main function of B cells is the recognition of foreign molecules to the body, called antigens, and the production of specific antibodies to neutralize them. After maturation, B cells are central cells in the adaptive immune response, they agglomerate in the lymph nodes, spleen and other lymphoid tissues, where they will come into contact with the antigens for which they are specific.
Candy bars are well known to supply large amounts of energy for metabolism. With all this energy trapped inside, how can the candy bar sit still on the shelf in the grocery store
Answer:
Energy is stored as potential energy
Explanation:
Candy bars are primarily made of glucose (and other types of sugars), which contain many covalent bonds that store potential energy. The reason why a candy bar can sit still on the shelf is because covalent bonds are very stable. However, when you eat the candy bar, your body has enzymes that can metabolize the candy, breaking down the covalent bonds and releasing all that "trapped" energy inside.

A characteristic is observed in an offspring that is not present in the parents. Which of the following
would cause a change in the phenotype of the offspring that was NOT present in the parent?
a mutation during cell replication in the parent body cells
a mutation during cell replication in the offspring sex cells
a mutation during gamete formation in the parent sex cells
a mutation during gamete formation in the offspring body cells
Answer:
C
Explanation:
A characteristic is observed in an offspring that is not present in either of the parents due to mutation during gamete formation in the parent sex cells. So the correct option is C.
What is heredity?The transmission of characteristics from parents to their biological offspring is called heredity. Heredity is apparent in sexual reproduction due to the high chances of variation.
The errors that might occur during the DNA replication result in the development of variations. The occurrence of variation is an important phenomenon for evolution to happen. Therefore, sexual reproduction is important for evolution.
Gene mutations and genetic recombination result in the development of variations. Asexual reproduction also gives rise to variations but those variations are not as apparent as in the case of sexual reproduction.
The mutations that happen in the gametes of parents during sexual reproduction may result in variation and thus the appearance of a new character in the offspring, that was absent in both the parents.
Therefore the correct option is C.

The yeast used to make beer can perform aerobic respiration or alcoholic fermentation. When O2 is available, yeast perform aerobic respiration, and when O2 is not available, yeast perform alcoholic fermentation. What is the advantage of aerobic respiration
Answer:
Aerobic respiration generates a high amount of energy compared to anaerobic respiration.
Explanation:
Yeast is a unicellular organism that belongs to the kingdom FUNGI. Yeast is a phenomenal organism being that it is capable of both aerobic respiration and anaerobic respiration depending on whether there is availability or not of oxygen.
Yeast undergoes a type of anaerobic respiration called FERMENTATION in the absence of oxygen but when oxygen is present, it undergoes aerobic respiration. Note that aerobic respiration, which includes glycolysis, Krebs cycle, and oxidative phosphorylation, produces the highest amount of energy in form of ATP. This amount ranges from 32-34 ATP molecules. This is the major reason why aerobic respiration is advantageous over the anaerobic respiration.

My pulse before the the jumping was slow and steadybuut after they were faster pace when I got done jumping. Their was a difference in the pulse rate it increases because your doing physical activity which cause you to pump more blood around.
There's a difference in the pulse of an individual after jumping because the pulse increases after physical activity.
A pulse rate simply refers to the measurement of the heart rate of an individual. It's also referred to as the number of times that the heart of a person beats per minute.
It should be noted that the pulse rate of a person will increase after an exercise. Therefore, after jumping, the pulse rate will increase. This means the heartbeats per minute rise.

D. 4.1
E 5.23
Answer:
A. 1.2
Explanation:
Normally, a human body cell contains 46 chromosomes - 23 inherited from the father and the same number from the mother.
Most of the human DNA, or human genes, are located in the chromosomes.
Each metaphase chromosome consists of:
two sister chromatids containing one DNA molecule each, and since they are formed by replication, these molecules are completely identical in gene content; that is why chromatids are called sister chromatids; two centromeres, one on each chromatid.
