The actual volume of bromine in each beaker will be same only the difference in height will be comparable. Therefore, option (C) is correct.

A liquid's attributes are;

1) Compared to the volume occupied by a gas, the volume of a liquid is relatively stable at conditions that allow it to remain in the liquid state.

2) A liquid will take the form of the container it is placed in.

3) A liquid's surface in a container must be flat for the attraction forces between its molecules to be in equilibrium both at the liquid's surface and within its body.

Therefore, there will be variations in the measured height of the same volume of bromine in each beaker given that the volume of the bromine is measured in a 50 ml beaker and a 100 ml beaker.

Explanation:

Answer:

The correct answer would be - a decrease in the numbers of RBCs will lead to a decrease in the ability for gas exchange in a person.

Explanation:

In the case of anemia, there would be a decrease in the number of RBCs that might be due to increased destruction of these cells, or low production of RBCs, that transporting oxygen and carbon dioxide affects the ability for gas exchange in an individual.

RBCs carry and transport oxygen to various body parts and then carry back carbon dioxide from different parts of the body to the lungs for gaseous exchange but with less number of RBCs leads to impair or decreased gas exchange in the case of anemia.

Answer:

The statement that says that In "gastrulation" cells begin to differentiate and they form different types of tissues so that they can accomplish different purposes in the body, is true.

Explanation:

Gastrulation involves a process of cell division, migration and differentiation, being one of the stages of embryonic development.

Cell differentiation and migration in gastrulation leads to the formation of germ layers, which are responsible for forming different tissues and fulfilling different functions in the body:

It is true, then, that In gastrulation cells begin to differentiate and form different types of tissues so they can accomplish different purposes in the body.

Answer: In amphibians, metamorphosis is generally associated with the changes that prepare an aquatic organism for a primarily terrestrial existence In  (frogs and toads), the metamorphic changes are more dramatic, and almost every organ is subject to modification Regressive changes include the loss of the tadpole's teeth and internal gills, as well as the destruction of the tail. At the same time, constructive processes such as limb development  are also evident. The means of locomotion changes as the paddle tail recedes while the hind limbs and forelimbs develop. The tadpole's cartilaginous skull is replaced by the predominantly bony skull of the frog. The teeth used for tearing pond plants disappear as the mouth and jaw take a new shape, and the tongue muscle develops. Meanwhile, the large intestine characteristic of herbivores shortens to suit the more carnivorous diet of the adult frog. The gills regress, and the gill arches degenerate. The lungs enlarge, and muscles and cartilage develop for pumping air in and out of the lungs. The sensory apparatus changes, too, as the lateral line system of the tadpole degenerates, and the eye and ear undergo further differentiation The middle ear develops, as does the tympanic membrane characteristic of frog and toad outer ears. In the eye, both ingratiating membranes and eyelids emerge.

Answer:

Lactic acid accumulation in the leg muscles

Explanation:

Muscle cramps are painful feelings caused by sudden contractions of the muscle. Cramps are caused by several reasons, however, based on the description of Akashay's activity, it is caused by ACCUMULATION OF LACTIC ACID in the leg muscles due to strenuous exercise.

According to this question, Akashay decided to run a marathon without any prior training. However, he started to get cramps on his thigh coupled with rapid breathing. There is a lack of oxygen in his cells, hence, anaerobic respiration was used leading to the formation of lactic acid. The buildup of lactic acid is what causes the painful sensation called CRAMP.

Answer:

Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation. Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population. Sexual reproduction promotes genetic variation by producing different gene combinations. Meiosis is the process by which sex cells or gametes are created. Genetic variation occurs as alleles in gametes are separated and randomly united upon fertilization.

Answer:

The dog breeder to check for all the details that meets her requirement of dogs.

Explanation:

A dog breeding is the practice of mating dogs. In the context, it is given that a dog breeder wants to purchase a male dog of three year old for her business and she founds an advertisement on the net about a purebred males that costs $700. Now before buying this purebred male dog, the dog breeder should first of all check whether the seller who is selling online is a licence breeder or not.

The dog breeder should also check whether the dog is a purebred or not and should also find out the actual age of the dog. The health of the dog should be checked by an professional vet before buying the dog.

The selling of dogs, either a hybrid or a purebred costs differently. An individual should check the license and health of the dogs before purchasing.

In the given example, the dog breeder is trying to purchase a three-year male dog. She saw an advertisement that the male dog is available at the rate of dollars 700.

Before purchasing the dog, the breeder should check:

Thus, the breeder should check all the authenticity of the dog and its health.

Answer: Friedreich ataxia is a genetic condition that affects the nervous system and causes movement problems. People with this condition develop impaired muscle coordination (ataxia) that worsens over time. Other features of this condition include the gradual loss of strength and sensation in the arms and legs; muscle stiffness (spasticity); and impaired speech, hearing, and vision. Individuals with Friedreich ataxia often have a form of heart disease called hypertrophic cardiomyopathy, which enlarges and weakens the heart muscle and can be life-threatening. Some affected individuals develop diabetes or an abnormal curvature of the spine (scoliosis).

Most people with Friedreich ataxia begin to experience the signs and symptoms of the disorder between ages 5 and 15. Poor coordination and balance are often the first noticeable features. Affected individuals typically require the use of a wheelchair about 10 years after signs and symptoms appear.

About 25 percent of people with Friedreich ataxia have an atypical form in which signs and symptoms begin after age 25. Affected individuals who develop Friedreich ataxia between ages 26 and 39 are considered to have late-onset Friedreich ataxia (LOFA). When the signs and symptoms begin after age 40 the condition is called very late-onset Friedreich ataxia (VLOFA). LOFA and VLOFA usually progress more slowly than typical Friedreich ataxia.

The genotype of the grandfather and the young man is ff (f allele for  Friedreich's ataxia) The genotype of the father and the mother is Ff.

A genotype is a classification of the type of variant found at a certain position (i.e., a locus) in the genome. Symbols can be used to symbolize it.

Friedreich ataxia is a hereditary disorder that causes movement issues by affecting the neurological system. This disorder causes decreased muscular coordination (ataxia), which worsens over time.

Individuals with Friedreich ataxia frequently have hypertrophic cardiomyopathy, a type of cardiac disease that enlarges and weakens the heart muscle and can be fatal. Some people who are impacted have diabetes or an irregular spine curvature (scoliosis).

Therefore, the genotype of the grandfather and the young man is ff (f allele for Friedreich's ataxia) The genotype of the father and the mother is Ff.

Answer:

This question is incomplete, however, it is asking to identify the following variables:

Independent variable: Temperature

Dependent variable: Number of yeast cells

Constants: same amount of nutrients, same number of yeast cells, same medium

Explanation:

- Independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable effect. In this experiment, the TEMPERATURE at which the yeast are kept is the independent variable.

- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable that is measured by the experimenter in the experiment. In this case, The NUMBER OF YEAST CELLS was counted, hence, it is the dependent variable.

- Constants are variables that are kept unchanged or same for all groups by the experimenter in order not to influence the experiment's outcome. In this case, the CONSTANTS are: same amount of nutrients, same number of yeast cells, same medium etc.
