Sickle cell anemia is a monogenic disorder in which the body produces abnormally shaped red blood cells. Sickle cell anemia is inherited in an autosomal recessive pattern. A person who is a carrier for this disease typically do not show signs and symptoms of the condition. Two cousins in Bangladesh got married and had kids without being aware that sickle cell disease runs in their family. Laboratory testing later showed that both partners were carriers for the sickle cell mutation. If this couple decides to have children, What is the chance (probability) that their children will also be carriers of the sickle cell disease?

Answers

Answer 1

Answer:

there's a ½ or 50% chance of their children will also be carriers of the sickle cell disease.

Explanation:

let IA = normal and IS =sickle cell

since both parents are carriers so it would be IAIS x IAIS

IAIS x IAIS

1 IAIA, 2 IAIS, 1 ISIS

Mitosis maintains chromosomes in each {blank} while meiosis maintains chromosome number in the {blank}.

Answers

Answer:

Mitosis maintains chromosomes in each cell division constant, while meiosis maintains chromosome number in half

Explanation:

Mitosis maintains chromosomes in each daughter cell while meiosis maintains chromosome number in the gametes.

What is mitosis and meiosis?

Mitosis is the process by which a cell divides into two identical daughter cells, each with the same number and type of chromosomes as the parent cell. During mitosis, the cell's DNA is replicated, and the replicated chromosomes are evenly distributed into the two daughter cells. This ensures that each daughter cell receives a complete set of chromosomes, maintaining chromosome number in the daughter cells.

Meiosis, on the other hand, is the process by which a cell divides into four non-identical daughter cells, known as gametes. During meiosis, the cell's DNA is replicated, and the replicated chromosomes are shuffled through a process called crossing over. This shuffling results in gametes with unique combinations of chromosomes, which helps to maintain chromosome number in the gametes. Gametes, also known as sex cells, are the cells involved in sexual reproduction, and they are important for maintaining chromosome number in offspring.

Answers

Hibernation is an adaptation that helps alpine animals to survive the cold winter. Hibernation helps to store energy.

Hibernation is an adaptation that helps to store energy by decreasing the metabolic rate.

This adaptation (hibernation) is observed in animals living in extremely cold conditions (e.g., alpine animals).

The hibernation adaptative strategy is characterized by an excessively low temperature in the body, slow breath rate, slow beats (heart rate), and low metabolic rate.

Answers

Answer:

Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake. The earthquake starts at the focus, with slip continuing along the fault. The earthquake is over when the fault stops moving.

Which of these graphs represents the effect of temperature on the rate of photosynthesis? Explain your answer.

WILL MARK BRAINLIEST!!

Answers

a. A describes the effect of light intensity on photosynthesis.

Answer: A

Explanation:
In plants and other primary producers, photosynthesis is a biological mechanism that is vital to energy production. Energy-containing carbohydrates are derived from light, water and carbon dioxide in the form of glucose molecules.
The waste product oxygen is released as a result. Photosynthesis depends on many variables, including:
carbon dioxide concentration,
ambient temperature
and light intensity
It is a rate-limited reaction. Since photons or particles of light provide the energy required for the reaction, high intensities of light increase the photosynthetic rate. From the graph shown, as the intensity increases steadily, so does the rate- but at too high of an intensity, it ceases to affect the rate of photosynthesis, which becomes constant or plateaus.
Beyond this point, either the supply of carbon dioxide or the temperature limits the reaction. For instance, at high intensities tissues may even be damaged by high temperatures or heat.

Graph A represents the effect of temperature on the rate of photosynthesis.

Why is photosynthesis affected by temperature?

Photosynthesis is a biological process that is essential to the synthesis of energy in plants and other primary producers. Light, water, and carbon dioxide combine to generate glucose molecules, which are the building blocks of energy-containing carbohydrates.

As a result, the waste product oxygen is emitted. Numerous factors affect photosynthesis, such as the amount of carbon dioxide present, the surrounding temperature, and the amount of light. It is a reaction with a rate constraint. High light intensities accelerate the rate of photosynthetic reaction because photons, or light particles, supply the energy needed for the reaction. According to the graph, the rate rises steadily as the intensity does, but at a certain point, the intensity stops having an impact and the rate of photosynthesis plateaus or becomes constant.

Beyond this point, the reaction is restricted by either the temperature or the carbon dioxide supply. For instance, at high intensities, heat or high temperatures may even harm tissues.

Answers

Answer:

D) Phylum

Explanation:

The group that was not present in the Linnaeus' system but is present in modern classification systems is Domain. The correct option is C.

What is Linnaeus classification system?

The Linnaean classification system is based on a hierarchy of groupings known as taxa. Taxa vary from kingdoms to species.

The kingdom is the most extensive and inclusive grouping. It is made up of organisms that have only a few basic resemblances.

The Linnaean system is significant because it paved the way for the use of binomial nomenclature to distinguish between species.

Scientists could communicate instead of using misleading common names once the system was implemented.

Domain is a group that was not present in Linnaeus' system but is present in modern classification systems.

Thus, the correct option is C.

Explanation:

1.There are some characteristics that are inherited from your parents, shape of blood cells is one of them. In sexual reproduction, offspring are formed when sperm of male combine with egg of female organism.Therefore, some characteristics comes from male organism and some from female organism. In sexual reproduction, diploid organism is formed because half of genes comes from male and half comes from female.

2.Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents

3.A monk, Mendel discovered the basic principles of heredity through experiments in his monastery's garden. His experiments showed that the inheritance of certain traits in pea plants follows particular patterns, subsequently becoming the foundation of modern genetics and leading to the study of heredit

4.Mendel made sure to study 30,00 pea plants when he presented his data to the community. Another example is when Mendel painstakingly removed all of the immature anthers from the plant’s flowers before the cross.Mendel used seven pea plant traits in his experiments which include flower color (purple or white), flower position (axil or terminal), stem length (long or short), seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted), and pod color (yellow or green).

5.A pea plant could have a copy of the height gene that coded for "tall" and a copy of the same gene that coded for "short." But the tall allele is "dominant," meaning that a tall-short allele combination would result in a tall plant
