From a classification standpoint, the crab organism is least like the other three. This is because all the given organisms are either amphibians or reptiles, but crabs are crustaceans.

Classification may be defined as an ordered set of related categories used to group data according to its similarities.

Crabs are crustaceans which are semi-aquatic creatures that have an exoskeleton, but alligators, frogs, and whales belong either to reptiles or amphibians.

C. Offspring were produced from different combinations of genes.

Explanation:

The offspring would not be adapting to different environments as they all live in the same aquarium. There is no mention of mutagenic agents present in the aquarium and that would have had more of an effect on the parents and not the offspring. The parents may have had different sets of alleles which could produce a variety of phenotypes of their offspring.

A waste product is a product that is made but isn’t necessarily needed eg. A lightbulb will make light energy but it also makes a waste product heat.

Waste products are nitrogenous wastes excreted from the metabolic processes. Uric acid is a waste product that uses maximum energy to produce. Thus, option B is correct.

Nitrogenous wastes are nitrogen-based products eliminated from the body in various forms like ammonia, urea, and uric acid. Ammonia has one nitrogen and is very toxic.

Urea has two nitrogen and is less toxic. On the other hand, uric acid has four nitrogens and complex molecules although is non-toxic but requires the maximum amount of energy to eliminate four nitrogen.

Therefore, uric acid needs maximum energy.

The complete question is attached to the image below.

Hi, The center image is a decomposer because it decomposes the dead organisms. The grass is a producer since it produces its own energy through photosynthesis. The rest are consumers because they consume other organisms to get energy. Hope that helped!

The grass is the producer, the grasshopper, rabbit, two birds, and the wolf are the consumers, and the fungus in the middle is the decomposer, as it decomposes everything after death.

In the food web, there are producers, like the green grass that is depicted here, that produce foods with the help of photosynthesis, which are later taken by consumers like the rabbit and the grasshopper. After the consumer and producer have died, all of these are decomposed by the fungi that are centrally present in order to maintain the nutrient cycle.

Hence, the grass is the producer, the grasshopper, rabbit, two birds, and the wolf are the consumers, and the fungus in the middle is the decomposer, as it decomposes everything after death.

The correct answer is B.

Answer:

The correct answer will be option B (Making short RNA primers)

Explanation:

Primase is a RNA Polymerase enzyme involved in the replication of DNA in organisms. for e.g- Dna-G (Prokaryotes) or AEP (Archaeo-Eukaryote Primase).

Role of primase in replication

1.Primase enzymes are activated by Helicase and form primosome complex.

2. Primase then synthesizes primers- short RNA molecules from ss-template DNA of 4-15 nucleotides long.

3.These primers are recognised by the enzyme DNA polymerase  which adds and elonagte  by adding nucleotides to the primer.

thus, option B is correct.

Answer: The shoot grows up towards the sunlight is Positive Phototropism

The root grows down the soil is Positively Geotropism / positive gravitropism.

happy to help again :)

Answer:

The correct answer is option B (negative gravitropism) and option C (positive phototropism).

Explanation:

Plant seedlings shows downward growth of roots and upward growth of stems due to response of plants to external environmental stimulus via a phenomemon known as tropism.

Plant tropisms are the result of differential growth as cells in area of stem or root grows more quickly than cells in opposite area.this growth determines the directional growth of the entire plants. The directional growth of an organism in response to light is known as Phototropism while directional growth of an organism in response to gravity is known as gravitropism.

Shoot growth in plants shows negative geotropism because they grow away from that force or in opposite direction of the gravity. Also, plants shows positive phototropism as they respond in direction of light.

Thus, option B (negative gravitropism) and option C (positive phototropism) are the right answer.

Answer:

Cones is the correct answer because cone is the female reproductive part

Answer:

Option C, Cones

Explanation:

In Gymnosperm,  male microspore and female megaspores are generated in sporangia which are carried by cones/strobili.  

Strobili consists of a short stem with leaves known as sporophyll on which sporangia is found. The sporangia producing the male microspore and female megaspore are found  on separate cones. The male cone is known as staminate cone and the female cone is known as ovulate cone.

Thus, option C is the correct answer

Answer:

You did not provide a figure, but you can refer to the attached picture and match it up with your figure.

The heart has 4 chambers. It has the left and right Atrium (plural is atria) and the left and right ventricle.

The blood FROM the body going towards the heart is deoxygenated. It empties into the RIGHT ATRIUM. From there, it goes through the tricuspid valve then empties into the RIGHT VENTRICLE. The right ventricle then pumps the blood up into the pulomonary artery, and goes towads the lungs to be oxygenated. The oxygenated blood then leaves the lungs via the pumonary vein and it empties the blood into the LEFT ATRIUM. From there the blood goes through the bicuspid valve and pours into the LEFT VENTRICLE. The left ventricle pumps the blood up the aorta and from there, it goes to the different parts of the body.

In summary:

BODY ---> RIGHT ATRIUM ---> RIGHT VENTRICLE ---> LEFT ATRIUM ---> LEFT VENTRICLE

Take note though that this is the pathway with regards to ONLY the chambers.

Answer:

Electrons become excited

Explanation:

After photons strike the light-absorbing pigment chlorophyll, electrons within the chlorophyll become increasingly excited. Only after this initial excitation do the electrons begin getting transported into the electron transport chain. Electrons in water molecules get released during photolysis, but only after they first become excited. ATP isn’t transformed into glucose until the light-independent stages of photosynthesis.

After photons strike the light absorbing pigment chlorophyll, the electron in that molecule becomes excited. The correct option is D.

Chlorophyll is the term coined to the green pigment used by plants to produce food throughout the photosynthesis process.

Chloroplasts are plant cell organelles that use photosynthetic energy to revert light energy into fairly stable chemical energy.

They endure life on Earth while doing so. Chloroplasts also perform a variety of metabolic functions for plant cells, such as the metabolism of fats and membrane lipids.

Chlorophyll is excited and emits electrons when it absorbs light. These chlorophylls are discovered in photosynthetic units known as Photosystems I and II.

Each unit has a distinct reaction center containing pigment molecules. These molecules absorb different wavelengths of light and emit electrons.

Thus, the correct option is D.

Answer: by adding the amplitude of the two waves

Explanation:

The question pertains to wave superposition in Physics, demonstrating constructive interference and standing waves when two identical waves intersect in opposite directions, leading to an increase in amplitude and fixed points of no motion (nodes) and maximum motion (antinodes).

The question deals with the concept of wave superposition in Physics, specifically the phenomena known as constructive interference and standing waves, which occur when two waves occupy the same place at the same time.

When two identical waves traveling in opposite directions intersect, they can add up at the same points in space, leading to an increase in amplitude. This process is called constructive interference, resulting in wave patterns called standing waves, characterized by their nodes—points where the amplitude is always zero—and antinodes—points of maximum amplitude. The figures mentioned in the question demonstrate these phenomena. For example, Figure 16.33 illustrates pure constructive interference where the amplitude of the resulting wave is twice that of the individual waves due to their perfect alignment in phase, whereas Figures like 12.1.1 and 5.6.5 show standing wave patterns resulting from the superposition.
