Movement of substances across a cell membrane without using energy is called active transport is true or false

Answer:

C

Explanation:

If Planet Y does not rotate on its axis at all, then one day-night cycle on the planet would take as long as one full orbit around the Sun.

This is because the definition of a day is the time it takes for one complete rotation on its axis, and if Planet Y does not rotate on its axis, it does not have a day.

Assuming that Planet Y's orbit around the Sun is circular and has a period of one Earth year (365.25 Earth days), then one day on Planet Y would also be 365.25 Earth days long. Therefore, a year on Planet Y would also be 365.25 Earth days long, and the planet would have one day and one night each year.

What is an orbit?

An orbit is the path that an object takes as it moves around another object due to the influence of gravity. In astronomy, the most common example of an orbit is the path that a planet takes as it revolves around a star. Orbits are governed by the laws of motion, particularly Kepler's laws of planetary motion, which describe how the gravitational force between two objects affects their motion.

Most antipsychotic drugs affect the activity of dopamine neurotransmitters in the brain. They work by blocking the activity of dopamine at its receptor sites.

This class of antipsychotic drugs is commonly referred to as dopamine receptor antagonists or dopamine antagonists. Dopamine is a neurotransmitter involved in various brain functions, including the regulation of mood, motivation, reward, and cognition. Dysregulation of dopamine neurotransmission has been implicated in certain psychiatric conditions, such as schizophrenia.. Antipsychotic medications, also known as neuroleptics, work by blocking dopamine receptors, reducing the effects of excessive dopamine activity. This helps alleviate symptoms associated with psychosis and contributes to the therapeutic effects of antipsychotic drugs. However, it's important to note that antipsychotic medications can also affect other neurotransmitter systems to varying degrees.

Deforestation is the process of cutting down trees by man, which eventually lead to the the sparseness of trees in otherwise forested areas. The reasons for cutting  trees by man may include: habitation by man, clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing as well as mining of minerals.

Deforestation leads to many adverse effects on both man and his environment. These adverse effects include:

Loss of biodiversity in the forests which may lead to extinction of species.; when forest areas are cleared, plants and animals who live in these forests lose their homes and some may eventually die off due to inability to survive in other habitats

Increase in temperature of the earth: Trees serves to cool the earth by removing some gases which cause heating of the earth from the earth. Such gases include carbon dioxide. When these tree are removed, these gases accumulate in the atmosphere leading to increase in earth's temperature.

Also, since tree absorb some gases while releasing others into the atmosphere, when these trees are cut, there would be an imbalance of these atmospheric gases.

E.  Dilute body fluids and a decrease in the osmolarity of interstitial fluids

Explanation:

When there is excessive water intake into the body, it can lead to water intoxication. It occurs as result of a combination of dilute body fluids and decrease in the osmolarity of interstitial fluids.

When excess water is taken into the body, the extracellular fliuds become very dilute, this results in a decrease in osmolarity , therefore, water will then move into the intracellular fluid by osmosis in order to establish equilibrium.. This causes the cells to swell, and in the brain, this swelling will result in increase in pressure within the cranium. This increase in pressure leads to the symptoms found in water intoxication such as nausea, confusion, and fainting. If not treated, it can result in death.

From the given options;

A. Dilute body fluids is only a part of the cause

B. Osmosis of water from ICF to ECF does not result in water intoxication because in water intoxication, water moves into the ICF from ECF

C. Decrease in water intake is wrong because it is an increase in water intake that results in water intoxication

D. Decrease in the osmolarity of interstitial fluids is only one part of the cause of water intoxication

E. Dilute body fluids and a decrease in the osmolarity of interstitial fluids is the correct option.

The cell type that would secrete its product if the body was under stress, as during an intense workout, is the pancreatic cell. However, it should be noted that there are different types of pancreatic cells, such as alpha and beta cells.

Alpha cells are responsible for producing glucagon, which raises blood sugar levels, while beta cells produce insulin, which lowers blood sugar levels. During an intense workout, the body requires more energy, and therefore, the pancreas will release more glucagon and insulin to regulate blood sugar levels and ensure that the body has enough energy to perform the physical activity.

Additionally, acinar cells are responsible for producing digestive enzymes, and they are not directly involved in regulating blood sugar levels during physical activity.

So, in summary, pancreatic cells, including both alpha and beta cells, would secrete their products if the body was under stress, as during an intense workout.

This is a simplified explanation of the DNA fingerprinting process, and there may be additional factors to consider when analyzing a specific DNA fingerprint.

To determine the genotype of the mother and father based on DNA fingerprinting,

you need to follow these steps:

DNA fingerprinting is based on the differences in the length of DNA fragments that result from cutting the DNA with restriction enzymes. The resulting fragments are separated by size using electrophoresis, which creates bands on the gel. Each band represents a fragment of a specific length.

The different alleles of a gene can have different numbers of tandem repeats, which will result in different fragment sizes. By comparing the size of the bands in the DNA fingerprint to a known set of alleles, you can determine the size of the alleles for each individual.

Based on the size of the alleles, you can determine the genotype of each individual. For example, if the alleles at a given gene locus are a1, a2, and a3, and one individual has alleles a1/a2 and the other has alleles a2/a3, you can determine the genotypes of both individuals.

Finally, you can infer the genotype of the parents based on the genotypes of their offspring.

For example, if two individuals have the same parents and one has the genotype a1/a2 and the other has the genotype a2/a3, you can infer that the mother is either a1/a2 or a2/a3, and the father is either a1/a2 or a2/a3.

Aboriginal people survive and thrive in the Australian environment by adapting themselves.

Pros: Northern Sydney was inhabited by many Aboriginal clans for thousands of years prior to the arrival of Europeans. They spent much of their time around the harbor's foreshore, where they fished, hunted, and foraged for sustenance in the region's waterways and hinterlands.

Cons: For Indigenous Australians, obstacles to accessing health care include lack of services in their neighborhood (especially for those living in remote areas), distance from services, and lack of transportation, cost, wait times, and the availability of culturally appropriate and responsive health services.

Thus, aboriginal people survive in Australia.

Answer:

C. 1.23 g/ml

Explanation:

\( Density = \frac{Mass}{Volume} \)

Mass of rock = 80g

Volume of rock = final fluid volume - initial fluid volume

Volume of rock = 265 cm³ - 200 cm³ = 65 cm³

\( Density = \frac{80g}{65 cm^3} \)

\( Density = 1.23 g/cm^3 \)

1 cm³ = 1 ml

Therefore, density of the object = 1.23 g/ml

Based on this information, scientists could predict that the base Adenine pair with Thymine and base Cytosine pair with Guanine in formation of the DNA molecule.

Base pairs are the building blocks of DNA molecule. The base pair consists of two nitrogenous bases that are complementary to each other and held together by hydrogen bonds.

Four types of nitrogenous bases in DNA are as : adenine (A), thymine (T), guanine (G) and cytosine (C). Adenine always pairs with thymine, and guanine always pairs with cytosine, following base-pairing rules of DNA. The sequence of these base pairs along the DNA molecule carries genetic information and determines the genetic code.

Answer: Bacterium inhaled from air alongside oxygen can be isolated by mucous membranes and eliminated by multiple immune defenses of the respiratory system.

Explanation:

The respiratory system consists of cilia and mucous membranes which lines the inner surfaces. These surfaces are made up of goblet cells which secrets a layer of sticky mucus. When microorganisms such as bacteria is inhaled along with oxygen, the viscosity and acidity of the sticky mucus inhibits microbial attachment to the underlying cells. The beating of cilia propels the mucus with any trapped bacteria towards the epiglottis where it is swallowed. This process of elimination prevents bacteria from further invading the lower respiratory tract.

Multiple immune defenses of the respiratory system includes:

--> mucosa associated lymphoid tissue (MALT): these includes adenoids and tonsils.

--> lysozyme

--> Surfactants

--> defensin (antimicrobial peptides)

--> alveolar macrophages

The activities of the multiple immune defenses of the respiratory system helps in the isolation and elimination of inhaled bacterium.
