What process is occurring in this picture at B?

Answers

Answer:

Translation

Explanation:

Translation is the second process that occurs in protein synthesis. It is the process whereby mRNA template is used to synthesize an amino acid sequence, which eventually becomes a protein.

The process of translation occurs in the cytoplasm (specifically in the ribosome). As depicted in this image, the mRNA produced during transcription is transported out of the nucleus into the cytoplasm. A RNA molecule called tRNA reads the mRNA sequence (codon by codon) and carries corresponding amino acid into the growing amino acid sequence.

Hence, according to this question, the process occuring at B according to this image is TRANSLATION.

1. Predict: How do you expect the spread of a foodborne disease to be similar to and different

from the spread of a person-to-person disease?

PLEASE ANSWER

Answers

Answer and Explanation:

The transmission of diseases through food and through people to people, are similar because both are caused by human contact with infectious parasitic agents such as bacteria and viruses. However, it is possible to notice some differences between these two types of transmissions.

Transmission of disease through food occurs when an individual eats contaminated food or drinks contaminated liquid. This contamination occurs due to the lack of hygiene of the handlers and storage problems, which can allow microorganisms, mostly bacteria, to grow in the food. Thus, when the contaminated food is ingested, the microorganisms will release toxins in the stomach that will cause disease. In the case of water, contamination can also happen due to the lack of basic sanitation and the incorrect dumping of garbage and human waste.

Diseases transmitted from person to person can occur in many different ways. One of the best known ways is through the contact of a healthy person with salivary goths or other body fluids of a person with the disease. However, this transmission can also occur through the contact of a healthy individual with the feces of a sick individual and even with physical contact with a sick individual.

left behind. Tubes take the urine from the kidney to a storage bag called the bladder.
What can you conclude about blood leaving the kidney?
A. It moves to the bladder.
B. It has no water left in it.
C. It is ready to be used by the body.
D. It needs to have urine added to it

Answers

Answer:

D. It needs to have urine in it

Explanation:

They are located just below the rib cage, one on each side of your spine. Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine. The urine flows from the kidneys to the bladder through two thin tubes of muscle called ureters, one on each side of your bladder. The fluid that is filtered out from the blood then travels down a tiny tube-like structure called a tubule. The tubule adjusts the level of salts, water, and wastes that will leave the body in the urine. Filtered blood leaves the kidney through the renal vein and flows back to the heart.

The two factors that determine the boundaries of a biome are temperature and precipitation, which are the second and third options, as they help to shape the unique features of each biome.

What is the significance of the precipitation and temperature?

Temperature plays a key role in determining the type of vegetation, such as in colder regions where low temperatures limit the types of plants that can grow, while in warmer regions the growth of tropical rainforests is seen. Precipitation plays an important role too, as in areas with high levels of precipitation, such as tropical rainforests, dense vegetation is seen, and in dry regions with low levels of precipitation, deserts are seen.

Heat energy = 12500 J

specific heat = 4.186

Formula:

The formula for Heat Energy is given by:

Q = mcp∆T

here: Q - Heat Energy

m is for mass

cp is for specific heat

∆T is a change in temperature,

Solution:

From formula,

m = Q/ cΔT

Mass = 12500 / (55 × 4200)

Explanation:

Plants can reproduce both sexually and asexually. What are some examples of sexual reproduction in plants? Select ALL that apply. Responses

Answers

Sexual reproduction in plants involves the fusion of male and female gametes to produce offspring with genetic diversity.

Mechanisms that facilitate sexual reproduction in plants are examples:

1)Pollination and Fertilization: Many plants rely on pollinators, such as bees, butterflies, or birds, to transfer pollen from the male reproductive structures (anthers) to the female reproductive structures (stigma) of flowers.

This process enables the fusion of sperm cells within the pollen with egg cells in the ovules, leading to fertilization.

Examples include flowering plants like roses, sunflowers, and apple trees.

2)Seed Production: After fertilization, the ovule develops into a seed. Seeds contain an embryo, formed by the fertilized egg, enclosed within a protective seed coat.

The mature seeds can disperse and germinate to give rise to new plants.

Various plant groups, including angiosperms (flowering plants) and gymnosperms (conifers and cycads), reproduce sexually through seed production.

3)Alternation of Generations: In plants with a complex life cycle, such as ferns, mosses, and liverworts, sexual reproduction involves an alternation between two distinct generations: the gametophyte and the sporophyte.

The gametophyte generation produces gametes (sperm and eggs) through specialized structures, while the fusion of gametes gives rise to the sporophyte generation, which produces spores.

4)Self-fertilization: Some plants have the ability to self-fertilize, where the pollen from the anther of a flower is transferred to the stigma of the same flower or another flower on the same plant.

This allows for sexual reproduction without the need for external pollinators. Self-fertilization can be seen in plants like tomatoes, peas, and certain grass species.

a.phenotype (yellow): genotype Aa
b.phenotype (red); genotype AA
c.phenotype (yellow); genotype aa
d.phenotype (red): genotype Aa

Answers

Answer:

d.phenotype red: genotype Aa

Explanation:

a red animal that is a Donna Mae a would still have dominance over the yellow animal it recessive so if you put it in the chart form AA would be on top and the lowercase a a would be on the left side so it would be phenotype red genotype capital a lowercase a .

In codominance, the genotype of the cross will be Aa and the phenotype will be yellow. Therefore, option "A" is correct.

What is codominance?

Codominance is a genetics-related term. The term means a type of inheritance, where two versions (alleles) of the same gene are expressed separately. This lead to the yield of different traits in the offspring. Examples are when in animals such as speckled chickens, having alleles for both types of feathers, black and white.

Roan cattle is also an example of co-dominance, which expresses alleles for both red hair and white hair. Codominance is also present in plants. Examples are rhododendrons which have a simultaneous expression of red and white genes for flower color display flowers with both red and white petals.

Topic 2: Employee Benefits & Effect of Covid-19 Pandemic on Post-employment benefit Plans Over the last two years, the global pandemic caused a sudden global decline in the price of equity securities and credit securities. Following this, many superannuation funds have shown negative returns on investments globally. Additionally, the rising Covid-19 cases and lockdown measures around the country and international borders have changed the way the people work and where they work, profoundly affecting employee short term benefits and superannuation plans and other benefits globally. Fiji was no exception to this. The first Covid-19 case, as discovered in Fiji in2020, led to closures of all borders, causing a massive economic downturn resulting in declining labour demand during the Covid-19 breakout period. While the government preventive measures in lockdowns led to the closure of all non-essential industries, business and activity sectors, the majority of the national employee population were at the height of losing their jobs.
