Answer:

A slope of 7, representing a speed 7 m/s.

Explanation:

Speed is defined as the distance traveled over time. Mathematically, it's calculated with the equation:

[tex]speed = \frac{distance}{time}[/tex]

Slope of a graph is the rate at which the y and x axis change together, the "rise over the run." Slope can be simply calculated using this equation:

[tex]slope = \frac{x_{2} - x_{1}}{y_{2} - y_{1}}[/tex]

Therefore, when graphing distance versus time, the change in distance is divided by the change in time to find the slope. This is the same as speed.

The DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells is nucleus.

The part of a cell that houses the chromosomes in biology. The membrane-enclosed nucleus is where RNA is synthesised from the chromosomal DNA.

DNA is organised into chromosomes in the nucleus, which is located in the centre of the cell.

The double nuclear membrane (outer and inner) that separates the nucleus from the cytoplasm, known as the nuclear envelope, envelops it. The rough endoplasmic reticulum and the outer membrane are one unit.

The nucleolus' main job is to facilitate ribosome biogenesis by assembling and digesting rRNA into preribosomal particles.

Bacterial cells lack the nucleus, the primary cell structure that houses DNA, that is present in plant and animal cells.

Thus, nucleus is only present is eukaryotic cells.

Answer:

the main causes are, infection,abdominal growth,inflammation,obstruction blockages

Explanation:

“Stomach cramps” is a general term that refers to sharp, intermittent contractions or feelings of pain or discomfort that occur anywhere in the abdomen between the lower chest and the pelvis or groin. The abdomen consists of many organs, including the stomach, intestines, liver, gallbladder, pancreas, esophagus, and numerous blood vessels.

Stomach cramps are a common symptom of a wide variety of mild to serious diseases, disorders and conditions that are often related to the abdominal organs and sometimes the pelvic organs, such as the uterus and bladder. Most people will experience stomach cramps at some point during their lifetime, and they can occur in any age group or population. Common causes of stomach cramps include indigestion, gastroenteritis, menstrual cramps, bladder infection, and excessive flatulence (gas).

Stomach cramps may be generalized, which means they occur throughout the abdomen. Stomach cramps may also be localized in a small area of the belly, such as the lower abdomen or pelvis near the groin, or in the upper abdomen where the stomach is located.

Depending on the cause, stomach cramps can last for a few minutes or hours, such as when they occur from indigestion due to eating rich food or from vigorous exercise. Stomach cramps can also last for a few days, such as when they are due to a menstrual period. Long-term stomach cramping may be continuous or occur periodically and may be due to more serious conditions, such as colorectal cancer.

In some cases, stomach cramps may be caused by serious conditions, such as food poisoning or colorectal cancer. Seek prompt medical care if your stomach cramps are unexplained, persistent, or cause you concern.

Stomach cramps may accompany other symptoms, which vary depending on the underlying disease, disorder or condition. If you have other symptoms along with stomach cramps, be sure to inform your health care provider. This information will help your doctor diagnose the reason for your stomach cramps.

Answer:

Homologous structure

Explanation:

Have a great day

Explanation:

The basic morphologies are spheres (coccus) and round-ended cylinders (bacillus). But there may be others such as helically twisted cylinders (spirochetes), cylinders curved in one plane (selenomonads) and unusual morphologies (such as the square, flat box-shaped cells of the archaean genus Haloquadratum).

Answer:

two homologous chromosomes travel together into one new daughter cell.

Explanation:

in metaphase I the tetrads line themselves up at the metaphase plate and homologous pairs orient themselves randomly. in anaphase I centromeres break down and homologous chromosomes separate. in telophase I chromosomes move to opposite pols; during cytokinesis the cell separates into haploid cells.

The characteristic that is shared by both primary and secondary consumers is that they gain energy by eating other living things. Therefore, option D is correct.

The primary consumers are the organisms that devour the producers. They are numerous and often modest in size. Herbivorous animals are the primary consumers (vegetarians). The organisms known as secondary consumers are carnivores that consume the primary consumers. Secondary consumers are consumed by tertiary consumers.

Herbivores, carnivores, omnivores, and decomposers are the four different categories of consumers in ecology.

The characteristic that is shared by both primary and secondary consumers is that they gain energy by eating other living things. Therefore, option D is correct.

Answer:

Explanation:

Earth's structures were created when the planet was first formed. Over time, its own gravitational and magnetic forces drove the Earth's core rotation.  Other geological activities affected its structures; such as glacial movements, tectonic plates collisions and submersion, volcanic eruptions and so on. There were also major external events the asteroid impact that killed most lives on Earth. Human activities' impact on Earth's structures were relatively small until the recent centuries.

Answer:

unicellular; multicellular

Explanation:

The smallest and the most basic unit of life is the cell. Living organisms that are made of just one cell are said to be unicellular while those that are made up of multiple cells are said to be multicellular. Many unicellular organisms are some of the smallest living organisms to exist in nature. They cannot be seen with the ordinary eyes, except with the aid of microscopes.

Answer:

t= log2(2048)

The logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x. In this case:

Answer:

Atoms used energy to make new molecules.

Explanation:

Atoms used energy to make new molecules through making bonds with one another because bonds allow atoms to attached tightly with each other. The energy come from the external environment in order to produce new molecules. So we can conclude that energy is the main ingredient needed for making new molecules and this energy is gained from the environment.

Explanation:

A farmer uses genetic engineering to inject dairy cows with a genetically altered hormone (GAH) to result in the production of more milk, and the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.

The GAHs that are used in dairy farming can result in an increase in the levels of hormones such as insulin-like growth factor 1 (IGF-1) in the milk, and these hormones can be harmful to human health and are also associated with an increased risk of certain cancers, such as breast cancer and In addition to concerns about the health effects of GAHs, there are also environmental concerns. The increased milk production resulting from GAH use can lead to overproduction, and animals get harmed by these genetically altered hormones.

Hence, the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.

Respuesta:

Las opciones correctas son: a) son de carácter antagónico, es decir el cloroplasto ejecuta reacciones anabólicas y la mitocondria catabólicas; y d) ambos son realizados por eucariotas pertenecientes al reino de los vegetales.

Explicación:

La fotosíntesis y la respiración celular son procesos de carácter antagónico porque la fotosíntesis es anabólica y la respiración celular es catabólica. La fotosíntesis consiste en la producción de moléculas complejas a partir de moléculas simples (proceso anabólico), mientras que en la respiración celular se degradan moléculas complejas y se las convierte en moléculas más simples (proceso catabólico).

Ambos procesos son realizados por los eucariotas del reino de los vegetales, pero los eucariotas del reino animal sólo realizan respiración celular, ya que no tienen cloroplastos. Esta diferencia tan importante existe porque los animales pueden moverse para conseguir comida (heterótrofos), mientras que los vegetales necesitan producir sus propios nutrientes haciendo uso de la fotosíntesis (autótrofos). Más allá de esta diversidad, todos los eucariotas realizan respiración celular para producir energía en forma de ATP.
