Answer:

1) B

2) A

3) C

4) C

5) A

6) D

7) A

8) B

9) B

10) A

11) B

12) C

Explanation:

1) This shows that the rock occupies space as what we are looking at here is volume. (The displacement of water) Let's look at each of the options. It doesn't show that matter has mass because there is no mass balance or any equipment to show the heaviness of the rock. The state of matter (options C and D) is not shown here as any matter, which occupies space, when poured or added to an already filled glass will cause the water to spill. Option C says that matter is a solid, which is false as there are many different states of matter, such as solid, liquid and gaseous state. While a rock is a solid, the statement that matters are solid is false.

3) The term space is not commonly used in the study of science, we usually call it volume. This is because 'space' is quite a vague word as it could mean atmospheric space. More precisely, volume is the amount (or measure) of space a matter occupies.

4) Weighing scale measures the amount of mass (or weight) in a body. Options A and D are units of measurement for length while B is used for volume. Recap: volume is the amount of space an object occupies

5) Here, we are differentiating matter from non -matter

Properties that differentiate a matter from a non- matter are mass and volume. Matters have mass and occupies space (have volume).

6) I. Light is not a matter

II. All matter

III. Heat is not a matter. It is the measure of coldness or hotness in a body.

IV. All matter

9) Option C talks about diffusion.

10) An ion is a charged particle. For example, if an atom gains or loses an electron, it becomes negatively or positively charged and is now known as an ion.

A molecule is a group of atoms bonded together.

12) Atoms are very tiny so centimeters and millimeters would be too big of a unit for measuring them. Gram is a unit of measurement of mass.

☆ Extra:

Mass is the amount of substance in a body while weight is the amount of gravitational force acting on a body.

Kidneys are often compared to filters because they cleanse unwanted waste from both frogs and humans true or false ?

PtichkaEL [24]

"Kidneys are often compared to filters because they cleanse unwanted waste from both frogs and humans" is TRUE.

Answer: Option A

Explanation:

Frogs also have the excretory system with two kidneys and similar to mammals. Its function is to eliminate the nitrogen product from the blood. Frogs make large volumes of dilute urine to wipe out harmful products from the tubules of the kidneys.

Tadpoles and aquatic frogs excrete the nitrogen as ammonia, but most terrestrial adults excrete it mostly as urea which is less threatening substance. A few tree frog species with little water access excrete the still less harmful uric acid.

Each of the four pedigrees that follow represents a human family within which a genetic disease is segregating. Affected individ

Ne4ueva [31]

Answer:

The following four traits are -:

Pedigree 1 - A recessive trait (autosomal recessive) is expressed by pedigree 1.
Pedigree 2- Recessive inheritance is defined by Pedigree 2.
Pedigree 3 - The inheritance of the dominant trait (autosomal dominant) is illustrated by Pedigree 3.
Pedigree 4- An X-like dominant trait is expressed by Pedigree 4.

Explanation:

Explaination of each pedigree chart-

Pedigree 1 demonstrates the recessive trait since their children have been affected by two unaffected individuals. If the characteristics were X-linked, in order to have an affected daughter, I-1 would have to be affected. $X^A$ In this, both parents are autosomal recessive trait carriers, so the child will be affected by a 1/4 (aa)
Recessive inheritance is defined by Pedigree 2. This is X-related inheritance as autosomal recessive inheritance has already been accounted for in part 1. This inference is confirmed by evidence showing that the father (I-1) is unaffected and that only the sons exhibit the characteristic in generation II, suggesting that the mother must be the carrier. The individual I-2 is a carrier for this X-linked trait. A typical Xa chromosome is attached to the unaffected father (I-1), so the chance of carrier II-5 is 1/2. Probability of an affected son = 1/2 (probability II-5 is a carrier) x 1/2 (probability II -5 contributes ( $X^A$ ) x 1/2 (probability of Y from father II-6) = 1/8. An affected daughter's likelihood is 0 because a typical $X^A$ must be contributed by II-6.
The inheritance of the dominant trait is demonstrated by Pedigree 3 because affected children still have affected parents (remember that all four diseases are rare). The trait must be autosomal dominant because it is passed down to the son by the affected father. There is a 1/2 risk that the heterozygous mother (II-5) would pass on mutant alleles to a child of either sex for an autosomal dominant feature.
Pedigree 4 is an X-linked dominant function characterized by the transmission to all of his daughters from the affected father but none of his son. On the mutant X chromosome, the father (I-1) passes on to all his daughters and none of his sons. As seen by his normal phenotype, II-6 therefore does not bear the mutation. An affected child's likelihood is 0.

In the question the pedigree chart was missing ,hence it is given below.

What happens when there is a high concentration of positive transcription factors but a low affinity for the positive transcript

Troyanec [42]

When there is a high concentration of positive transcription factors but a low affinity for the positive transcription factor

Transcription factors are proteins that regulate the transcription of genes—that is, their copying into RNA, on the way to making a protein.

Proteins called transcription factors, however, play a particularly central role in regulating transcription. These important proteins help determine which genes are active in each cell of your body.

<h3>How does transcription factors affect gene expression?</h3>

Under the influence of transcription factors, the various cells of the body can function differently though they have the same genome. Transcription factors attach to one or more series sites, which are called transcription element binding sites (TFBSs), binding to specific DNA sequences of the genes they control
