Cells transport molecules into the cell in many different ways. One method is through endocytosis, shown in the model. In endocytosis, the cell brings specific molecules it needs, including fluid, into the cell. Why does the structure of the plasma membrane make this type of transport necessary for fluids?

Answer:

The correct answer is - ionic bond.

Explanation:

Ionic bonds are the bonds that are formed when an atom transfer its electron to the other atom and forming ions that become electrically charged that attracts each other and form bond between them.

Given the picture showing the ionic bond formation as sodium transfers one electron to the chlorine ion and becomes electrically charged and therefore electrically attracted to one another to form an ionic bond.

Thus, the correct answer is - ionic bond.

Fat molecule

Explanation:

A fat molecule comprises of a backbone which is made up of glycerol and a tail which is made up of three fatty acids. Glycerol can be described as a tiny molecule which is made of just three hydroxyl groups (OH) whereas fatty acids are long compounds comprising long chains of hydrocarbons. These hydrocarbons are attached to the carboxyl group. Normally, fatty acids contain 12 to 18 hydrocarbons but can carry as low as 4 and as high as 36 hydrocarbons.

Answer:

Each parent organism contributes one copy of its alleles in a seemingly random fashion to its offspring, as meiosis to create gametes (egg or sperm cells) reduces the number of genes by half. Therefore, each gamete contributes only one allele.

Explanation:

During meiosis process each parent contribute haploid gamete with an alleles for a specific gene in a random fashion to its offspring,  Therefore, each gamete contributes only one allele.

Alleles are the forms of a gene which carry a trait, it is present in a pair in a specific location on a particular chromosome and control the same trait.

Alleles of an organism makes the genotype.

If a pair of alleles are similar for a trait, then the genotype is homozygous.

If the pair of alleles are different for a trait, then the genotype of the organism called as  heterozygous.

Similarly in a heterozygous genotype, the allele which express its character called dominant allele and the other one which wont express called recessive allele.

For example, the human blood group ABO.

Answer: Lemon juice- Independent variable

Intensity of brown color color of apple -Dependent variable

Explanation:

Independent variable can be defined as the factors which the experimenter can control and the the dependent variable depends on the independent variable.

Here, the experiment is to test the effect of lemon juice on the color intensity of apple( basically the brown color).

The color change is based on whether lemon juice is sprayed on the half part or not and it is kept for 4 days. The color change is then observed.

Based on this the hypothesis is accepted or rejected.

The experiment's independent variable is lemon juice presence on apple slices, testing its impact on browning (dependent variable) after 4 days, observing if acidity reduces enzymatic browning.

In this experiment, the independent variable is the presence of lemon juice on the apple slices. It is manipulated by spraying half of the slices with lemon juice and leaving the other half untreated. The dependent variable is the degree of browning observed on the apple slices after 4 days of storage in a sealed plastic bag. The degree of browning is a result of the interaction between the apple's natural enzymes and the oxygen in the air.

By introducing the lemon juice, which contains antioxidants like ascorbic acid, the experiment aims to test whether the acidic environment created by the juice can slow down the browning process by inhibiting the enzymatic reaction. The independent variable (lemon juice) is hypothesized to affect the dependent variable (degree of browning).

Amplifying, in the context provided, usually has a positive connotation as it describes enhancing electrical signal strength. However, connotations can vary depending on the context, and in academic writing, a neutral to positive connotation is often sought.

Explanation:

In the context provided, the term amplifying refers to the process of increasing the strength of a weak electrical signal without changing its other characteristics. The word amplifying itself does not innately possess a positive or negative connotation; its connotation depends on the context in which it is used. In the context of electronic amplification, the term is generally considered positive because it describes the enhancement or improvement of signal strength. However, when used metaphorically or in different contexts, the connotation may change. For example, amplifying negative attitudes or information might be seen as a negative action.

Connotations are important in both spoken and written language, as they can influence the reader's or listener's perception of the subject being discussed. Academic writing typically strives for a neutral to positive connotation to maintain a professional tone.

Answer:

As the size of a star increases, luminosity increases. If you think about it, a larger star has more surface area. That increased surface area allows more light and energy to be given off. Temperature also affects a star's luminosity.

Explanation:

A star is a gas ball that is luminous that can be hydrogen and helium, and stay in position by its own gravity. As the mass of star increases, the luminosity of it also increases.

Luminosity is the total amount of energy emitted by a star or other celestial object per second.

The power output of a star along with the wavelengths is called its bolometric luminosity.

The increased surface area of star promotes more light and energy formation. It can also be affected by temperature.

Thus, as the mass of star increases, the luminosity of it also increases.

Answer:

Yes.

Explanation:

In the tropical Pacific, like the western coast of central and south America, the surface of the sea is cooler than normal and that results in reduced rainfall, drought and increased fires. This definitely brings about a negative effect on wildlife, as there is less water and food available.

However, in South East Asia, a higher than normal rainfall is commonly experienced, which is good for agriculture.

Final answer:

A La Niña event, characterized by cooler Pacific Ocean water, affects global weather and ecosystem dynamics. Marine wildlife may benefit from increased nutrient availability, while terrestrial wildlife could be stressed by altered weather patterns. The overall impact on wildlife is complex, with some species benefiting and others facing challenges due to ecosystem fluctuations.

Explanation:

A La Niña event, which is a period when the Pacific Ocean is cooler than usual, has significant impacts on global weather patterns and consequently on wildlife. During La Niña, stronger trade winds blow across the Pacific, leading to a buildup of cooler water in the western Pacific compared to normal years. These cooler ocean temperatures can affect global weather patterns, potentially leading to more intense storms in some regions, droughts in others, and fluctuations in marine ecosystems.

For instance, marine wildlife is impacted by changes in ocean temperatures and currents. A cooler ocean can lead to an increase in upwelling, which brings nutrient-rich waters to the surface and can boost plankton populations. This effect can lead to a more abundant food supply for fish and other marine organisms, potentially increasing their populations. However, terrestrial wildlife may experience stress due to altered weather patterns, such as increased rainfall or drought conditions, which can affect their habitats and food availability.

Moreover, La Niña can influence the migration patterns of birds and marine animals, as they respond to changes in food availability and habitat conditions. Additionally, the populations of prey species can fluctuate, affecting predators and the overall ecosystem balance. It's important to note that while some species may benefit from the conditions brought about by La Niña, others may face greater challenges. Overall, wildlife impact during La Niña events is complex and varies across different ecosystems and species.

Answer:Answer: C- it is Gly, Ser, and Arg

Explanation:

Answer:

C. Gly-Ser-Arg

Explanation:

Gene expression is an important process in living cells as it involves the synthesis of useful products (proteins) needed for optimal functioning of the cell. Gene expression occurs in two major stages viz: transcription and translation. Transcription involves the synthesis of a mRNA molecule using a DNA template.

Translation, on the other hand, occurs in the ribosome (organnelle for protein synthesis). The mRNA molecule produced during transcription is read in a group of three nucleotides called CODON. Each codon specifies a particular amino acid i.e. as one codon is read, one amino acid is added to the polypeptide chain (future protein).

Based on this, a mRNA molecule with a sequence: GGU AGC CGG is composed of three codons, which codes for three amino acids. Using the genetic code provided as an attachment to this question,

Codon GGU codes for Glycine (Gly) amino acid

Codon AGC codes for Serine (Ser) amino acid

Codon CGG codes for Arginine (Arg) amino acid.

Hence, GGU AGC CGG mRNA sequence will synthesize an amino acid sequence: Gly-Ser-Arg.
