False, timing of a mutation during development has no negligible effects on the severity of the genetic defect.

Mutation are considered as beneficial, harmful, or neutral, depending on their context or location. Many of the non-neutral mutations are deleterious. In general, if the larger number of base pairs are affected by mutation, the impact of mutation will be greater, and the larger the mutation's probability of being deleterious.

Mutations can also result from errors in DNA replication during cell division, reason can be the exposure to mutagens or a viral infection. Germline mutations can be passed on to offspring, while somatic mutations cannot be transferred.

If a guard cell expressed a potassium channel that constantly pumped potassium into the cell, then the b) stomata would always be open.

When potassium ions will be pumped into the guard cells constantly, the level of water inside the guard cells will decrease. In other words, the amount of solute will increase and the amount of solvent will decrease.

As a result, more amount of water will be pumped from the roots to the guard cells. This will cause the water concentration to also increase. Hence, the guard cells will open the stomata so that all of the excess water that has been transported to the guard cells could be removed into the environment.  The guard cells will close once the pottasium channel is disturbed.

Although a part of your question is missing, you might be referring to this question:

The cell cycle's longest phase is called interphase. Before starting mitosis, cell develops and duplicates its DNA in this phase. Chromosomes line up, split, and move into new daughter cells .

In prophase, the chromosomes get shorter and thicker. chromosomes comes in the middle of the cell, during the metaphase, the chromosomes align. Chromatids break during the anaphase process and move to the opposing poles. Telophase: Two nuclei are formed when nuclear envelopes have reformed around chromosomal group.

If the non-template DNA strand's 5′ 3′ nucleotide sequence is CAT, the equivalent codon on the mRNA will be CAU. Prior to the corresponding codon being read on mRNA, DNA must first be transformed into RNA.

The DNA strands are complementary and anti-parallel for both the coding (or sense) and the template (or non-coding, or anti-sense). In order to produce a complementary RNA that is in the 5' to 3' direction during transcription, the RNA polymerase "reads" the template strand in the 3' to 5' way. The coding (or sense) strand of DNA discloses the meaning of the RNA since the template strand of DNA is complementary to both of them, with the exception that all Ts in the coding strand are changed to Us.

Single-character hybrids, also known as monohybrids, are the offspring of two true-breeding parents who differ in just one character.

Monohybrids did not exhibit an intermediate trait, but rather resembled one of the two parents. The monohybrids show the trait and the trait is disguised when two true-breeding plants that are different in only one characteristic are crossed. The number of traits being studied in the progeny is the primary distinction between monohybrid and dihybrid crosses. One trait is expected to be inherited in a monohybrid cross. Monohybrid crossings occur when the parents are homozygous for the same trait but differ in another characteristic.

The majority of animals must keep their internal body temperatures within a relatively small range. Endotherms keep their bodies warm by producing heat within.

Animals that employ metabolic heat production to maintain a steady body temperature are known as ectotherms. Instead, their body temperature varies in accordance with the ambient temperature.

Ectotherms, on the other hand, depend on behavior to control their body temperature. To cool off or warm up, they must move their bodies toward the sun or shade. In comparison to ongoing metabolic regulation, this uses less energy. This explains why many reptiles and other ectotherms may consume a substantial meal once and then go for a while without eating.

The phase of mitosis given by the letter 'C' here is Metaphase.

In the process of mitosis,  a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The term "mitosis" means " threads," and it is referred to the threadlike aspect of chromosomes as the cell prepares to divide. The process of mitosis consists of five morphologically distinct phases prophase, prometaphase, metaphase, anaphase, and telophase.

The metaphase begins as soon as the prometaphase ends and then the chromosomes align along the cell equator. Every chromosome has at least two microtubules extending from its kinetochore with at least one microtubule hitched to each pole. At this particular juncture, the pressure within the cell becomes balanced, and the chromosomes no longer move back and forth. In addition, the spindle is now complete , and three groups of spindle microtubules are evident. Kinetochore microtubules attach the chromosomes to the spindle pole; interpolar microtubules extend from the spindle pole across the equator, nearly to the contrary spindle pole; and astral microtubules draw out from the spindle pole upto the cell membrane. One of the cell cycle checkpoints happens during prometaphase and metaphase.

Answer:

C. A saltwater fish (salinity 35ppt) is moved to a freshwater tank (salinity 0.5 ppt). The fish shrivels and diesas water moves from an area of high concentration to an area of low concentration.

Explanation:

Fresh water—less than 0.5 parts per thousand (ppt) Fresh water contains trace amounts of salt and other dissolved substances at very low concentrations.

Freshwater salinity is usually less than 0.5 ppt. Water between 0.5 ppt and 17 ppt is called brackish. Estuaries (where fresh river water meets salty ocean water) are examples of brackish waters.

Different bodies of water have different amounts of salt mixed in, or different salinities. Salinity is expressed by the amount of salt found in 1,000 grams of water. Therefore, if we have 1 gram of salt and 1,000 grams of water, the salinity is 1 part per thousand, or 1 ppt.

The average ocean salinity is 35 ppt. This number varies between about 32 and 37 ppt. Rainfall, evaporation, river runoff, and ice formation causes the variations. For example, the Black Sea is so diluted by river runoff, its average salinity is only 16 ppt.

The pollen tube will form, but it will not be directed toward the egg to be fertilised.

When the haploid megaspore nucleus divides, an embryo sac is said to form. It has two haploid nuclei and six haploid cells with no cell walls. In some cases, the haploid nuclei join together to form a single cell (endosperm motor cell). At the time of fertilisation, one male nucleus and one egg nucleus combine to form a zygote, which leads to the development of the embryo. The primary endosperm nucleus and the second male nucleus fuse to form the endosperm nucleus. A pollen tube develops into one of the female gametophyte's two synergid cells during the angiosperm fertilisation process.

Cell death occurs in the synergid cell into which the pollen tube grows, either before or after the pollen tube enters this cell. Synergid cells direct pollen tube growth toward the female gametophyte and aid in tube entry into the embryo sac.

Glucose and oxygen are the products that result from photosynthesis and that also serve as the starting materials for cellular respiration.

Plants are the most well-known examples because, with the exception of a very tiny number of parasitic or mycoheterotrophic species, they all possess chlorophyll and are capable of producing their own food. The algae make up the other significant class of eukaryotic photosynthetic organisms.

The main purpose of photosynthesis is to transform solar energy into chemical energy, which is then stored for use later.This technology is mostly used to supply energy to the planet's biological processes. According to human engineering standards, it is not particularly effective, but it gets the job done.
