Answer:
c. They produce functional β-galactosidase that cleaves X-gal.
Explanation:
β-galactosidase is an enzyme capable of catalyzing the enzymatic hydrolysis of β-galactosides into monosaccharides by hydrolyzing the β-glycosidic bond. On the other hand, X-gal is an analog of lactose composed of galactose, which is widely used in laboratories for the detection of β-galactosidase. In the presence of β-galactosidase, X-gal is hydrolyzed by cleaving its β-glycosidic bond, thereby confirming the presence of β-galactosidase.

Explanation:
Lycopodium is known as as ground pine, and is a genus of clubmosses. They are homosporus, because they produce only one type of sporangia, while Selaginella are heterosporus, because they produce microspores and megaspores, and they are known as spike moss. Both of them, lycopodium and selaginella can have strobili.
Which structure in plants produces a substance that protects the extending roots from developing friction?
a.root cap
b. stele
c.stem
d.epidermis
Answer:
The correct answer is - option a. root cap.
Explanation:
Roots of the plants are developed from the structure called radical in seed during germination of seed.The tip of the root is tender due to the present of the apical meristem that is the precursor of the new cells of the root and protected by the root cap and penetrate in to the soil with the help of mucigel. Mucigel is the which protects the extending roots from developing friction.
Thus, the correct answer is : option a. root cap.
Answer:
The answer is ROOT CAP

Our solar system is found near the inner edge of large Scutum-Centaurus Arm of the Milky Way. True or False?
Answer:
true
Explanation:
Using specific examples, discuss the roles of negative and positive feedback processes that maintain homeostasis.
Answer:
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

This category of plants does not have vascular tissue or seeds. Question 3 options: Angiosperms Gymnosperms Ferns Mosses
Answer:
Mosses
Explanation:
Mosses are the category of plants that does not have vascular tissue or seeds while angiosperm, gymnosperms, and ferns have vascular tissues and seeds.
Due to absence of vascular bundles or veins, the mosses also lack stems, true roots, and leaves. some of the examples of mosses are: liverworts, hornworts, and Ricceia natans etcetera.
Hence, the correct answer is "Mosses".
Answer:
Mosses
Explanation:
Mosses are the category of plants that do not have vascular tissue or seeds. Ferns do not have seeds, but do have vascular tissues. Angiosperms and gymnosperms have vascular tissue and seeds.

A researcher discovers that polar bears have very good insulation and very think hair (similar to pandas). However, they do not show the rest of the panda behaviors. For example, they have high daily energy expenditure and are very active. Why are the panda and polar bear so different
Answer:
Panda and polar bear have some similar characteristics but they also have differences in their behaviors such as polar bears have high daily energy expenditure and are very active while pandas are not.
The panda and polar bear so different because of the geographical difference where they live.
Polar bears are marine mammals and live in north pole perform swimming in north oceans and also move on ice flows, where they catch seals for survival, it makes them active and energetic.
While Pandas are found in China bamboo forests and are herbivores. They eat leaves from bamboo trees, for which they do not require to be more active and get their food easily. So, Pandas are not active as polar bears.
As the climate of North pole and China is cold, both polar bear and panda have very good insulation

in the fruit fly, the long wing allele is dominant over the short wing allele. What are the parental genotypes for a cross that yields 75% long winged offspring and 25% short winged offspring.
According to the scenario, the parental genotypes for a cross that yields 75% long-winged offspring and 25% short-winged offspring are Ll and Ll.
What are Genotypes?Genotypes may be defined as the ultimate combination of alleles of those genes which are significantly taken for specific studies.
According to the context of this question, in the fruit fly, the long-wing allele is dominant over the short-wing allele. This means that capital L is dominant over small l. So, the genotypes LL and Ll govern the dominant trait, i.e. Longwing.
The Punnett square for the given cross is as follows:
Therefore, the parental genotypes for a cross that yields 75% long-winged offspring and 25% short-winged offspring are Ll and Ll.

Answer:
This question lacks options, options are:
A) cerebral cortex.
B) basal nuclei.
C) sensory pathways.
D) motor pathways.
E) All of the answers are correct.
The correct answer is E.
Explanation:
The cerebral cortex processes and filters its information before passing the most relevant aspects to other regions of the brain. Some of these brain regions, in turn, send information back to the cortex. These loops, known as 'feedback systems', are considered essential for the functioning of cortical networks and their adaptation to new sensory information. Neural circuits must first assess the importance of incoming sensory information and then refine how it is processed in the future. Positive feedback, triggered with the purpose of amplifying the response to the initial stimulus, can be compared to a chain reaction or a vicious circle. Few are the functions regulated by this mechanism; rather it is triggered in pathological situations. It is the system by means of which the organism very rarely regulates any of the bodily functions under normal conditions, making the initial stimulus to be maintained and even increased. This type of mechanism is predominantly present in pathological situations: Its constitutive elements are: stimulus, receptor, afferent pathway, integrating center, efferent pathway, effector and response. The response does not have the ability to satisfy the initial stimulus.
The main evolutionary consequence of the process of 'plate tectonics' has been
The movement of plate tectonics produces new environments and gives organisms a new environment that they now need to adapt and evolve to fit into.

Bats have oversized ears, which help the bad you sound waves to detect the motion of their prey which example of the characteristics of life is most similar
A) A yeast cell splits itself in half to create a new organism.
B) A rat hides in its hole when it sees an approaching predator.
C) A fungal cell releases carbon dioxide back to the atmosphere.
D) A human child grows taller every year.
The answer to this question is B) A rat hides in its hole when it sees an approaching predator.
Explanation:
One of the characteristics of living organisms is the ability to adapt or respond to the environment. This feature of life is the one shown by bats in this case because the oversized ears are a result of evolution and adaptation that help bats to have more chances of survival. Similarly, rats hiding to avoid predators is a result of adaptation that helps rats survive by avoiding predators. Thus, rats and bat show the same characteristic of life.
