Answer:
The correct answer is - h(omo)zygous recessive
Explanation:
When a cross between the organism with dominant phenotype, that can be heterozygous genotype or h(omo)zygous genotype, with a organism of h(omo)zygous recessive takes place, the cross known as test cross.
Test cross always exhibit an individual with the dominant phenotype. he aim of test cross is to find if the dominant individual is h(omo)zygous or heterozygous.
Thus, the correct answer is - h(omo)zygous recessive.

A microscope that is calibrated this way will maintain the specimen in focus when the objective lens is rotated.
● Pointer
● C-mount
●fine focus
●Parfocal
Answer:
The correct option is;
Parfocal
Explanation:
A perfocal lens is one that when in use, the object remains in focus when the objective lens is rotated to change the magnification power of the microscope. That is the when the magnification is adjusted, the objectives remains in focus. The use of the parfocal lens however results in a small but insignificant amount of error in the focus.
plzz help Is pollination of a flower the “intention of a pollinator? Why or why not?
Some plants self-pollinate, that is, pollen transfer occurs within the same flower or among the flowers on a single plant, usually because the anthers touch the adjacent stigma. The majority of flowering plants, however, depend on the transfer of pollen from other individuals (cross-pollination).

Which region of myosin interacts with actin filaments? A. the head domain B. the rod domain C. the light chains D. the tail domain
Answer:
A. the head domain
Explanation:
The head domain of the myosin interacts with the actin filaments. It binds to an active site on the actin producing an inclination of the myosin head and the hydrolysis of ATP. As a consequence of these changes, the myosin has the necessary energy and is in the right position, ready to move along the actin filament producing the contraction of the muscle.
The French scientist Jacques Monod famously said, "Anything found to be true of E. Coli must also be true of elephants." How is this statement based on the notion that living organisms share a common ancestor?
Answer:
The correct answer is : prokaryotic organisms like E. coli and higher organisms share common ancestor.
Explanation:
E. Coli is a prokaryotic organism or bacteria. On the metabolic level these organisms share similar homology with the higher organism other than this these organisms also show same core functions with higher level organisms such as elephant.
These similarities suggest that the all the living organisms share a common ancestor. The french scientist Jacques Monod statement "Anything found to be true of E. Coli must also be true of elephants." is also based on this notion.

Lions and cheetahs prey on wildebeests that graze in the grasslands of the African savanna. What likely effect would increased rainfall over several rainy seasons have on the populations of wildebeests, lions, and cheetahs?
This question is incomplete because the options are missing; here is the complete question:
Lions and cheetahs prey on wildebeests that graze in the grasslands of the African savanna. What likely effect would increased rainfall over several rainy seasons have on the populations of wildebeests, lions, and cheetahs?
A. All three populations would increase.
B. The wildebeest population would decrease, and the lion and cheetah populations would increase.
C. The wildebeest population would increase, and the lion and cheetah populations would decrease.
D. All three populations would decrease.
The answer to this question is A. All three populations would increase
Explanation:
Grass, wildebeests, lions, and cheetahs are part of the same food chain and due to this a change in grasses due to rainfall will affect the other species. In this context, an increase in the rainfall is likely to increase the availability of grass because grasses thrive and develop better with more rainfall. This change would cause the population of wildebeests to increase due to an increase in the availability of food. At the same time, it is likely cheetahs and lions increase because similar to wildebeest these species will have more food available, which makes it easier to survive and reproduce. This means in this situation the three populations would increase.
Answer:
All three populations would increase.

Explain the difference between local extinction and species extinction.
Answer:
local extinction, is the disappearance of a species only from a given area and species extinction is the extinction of a species everywhere
Explanation:
The difference between local extinction and species extinction is local extension refers to when the species extinct from a local area and species extinction refers to the extinction of that is species from all over the Earth.
What is extinction?Extinction is a process by which an animal or any other organism or a thing has completely been destroyed from a place or from all over the Earth.
Extinction of species is becoming a common thing due to the over-exploitation of human activities. Many species extinct and many species are in the stage of extinction.
When a species is extinct in a local area, but it is present in another area, it is called local extinction. When a species extinct from or all over the world. For example, the dodo bird is extinction completely from the earth.
The distinction between local extinction and species extinction is that the former relates to the extinction of a species within a specific geographic region, whilst the latter refers to the extinction of a species globally.

What safety equipment is required for the Osmosis Experiment? Justify why the equipment
is needed.
Answer: Wear eye protection, rubber gloves
Handle acid with care and follow CLEAPSS or SSERC guidelines on its use.
The safety equipment which is required for the Osmosis Experiment is as follows:
The goggles protect the eyes. The gloves ensure the safety of hands. Handle chemicals such as acids with extreme care.Follow the systematic guidelines and protocols of the laboratory. What is an Osmosis?Osmosis may be defined as a process through which the molecules of a solvent be inclined to pass through a semipermeable membrane from a region of less concentrated solution into a more concentrated one.
During the whole setup of this experiment, numerous chemicals, as well as, instruments are required. So, in order to ensure your safety, try to follow all the basic and fundamental protocols of the laboratory along with that of the experiment.
Equipment assists or saves you in situation where a certain mistake is has happened. For example, if a drop of acid falls on hand, assume what will happen when you are without gloves? This is the importance of safety equipment.
Therefore, the safety equipment which is required for the Osmosis Experiment are goggles, gloves, systematic protocols, etc.

A student conducts an experiment by placing a wooden stick in a cup of sugar solution. Over the next few weeks, sugar crystals form on the stick and increase in size. The student concludes that the resulting crystals must be alive because they grow. Rock candy, which is a collection of large sugar crystals that have crystallized around a wooden stick from a sugar solution. 4. What is wrong with the student’s conclusion, and how can it be corrected?
Answer:
In order to be alive, there must be cell(s) present. Since sugar does not contain cells, it is not alive.
Explanation:
In order to be alive there should be cells gift and given that sugar does now no longer incorporate cells it isn't alive.
What is supersaturated solution?A supersaturated solution is unstable—it incorporates greater solute (on this case, sugar) than can live in solution .

The climatology method would be the best to forecast weather conditions that will occur exactly one year from today.
What do you mean by climatology?Climatology is the study of the atmosphere and weather patterns over time. This field of science focuses on recording and analyzing weather patterns throughout the world and understanding the atmospheric conditions that cause them.
Moreover, it is important since it helps determine future climate expectations. Through the use of latitude, one can determine the likelihood of snow and hail reaching the surface. You can also be able to identify the thermal energy.
These elements are solar radiation, temperature, humidity, precipitation (type, frequency, and amount), atmospheric pressure, and wind (speed and direction).
