Answer:

denial is usually the first reaction

The correct answer is B. The scientists' findings show that when the salt concentration was high, lobsters were more likely to avoid shelters with cues from diseased lobsters.

This supports the argument that information lobsters receive through sensory receptors can cause immediate changes in behavior because the presence of chemical cues from diseased lobsters triggered a response in the lobsters, causing them to avoid the area. The fact that the response was more pronounced when the salt concentration was high suggests that the lobsters are more sensitive to these cues under certain conditions, which reinforces the idea that sensory receptors play a crucial role in their behavior. The other options do not provide evidence to support this argument, either because they do not involve immediate changes in behavior or because they do not relate to the role of sensory receptors.

Answer:

The observed image will not be sharp

Explanation:

When 100x microscope objective lens is being used, light refraction in the air is enough high to produce image alterations. Image distortions can be minimized by immersion oil because this liquid has a higher refractive index than air. However, light refraction is not usually noticeable when using 4x, 10x and 40x objective lenses. Moreover, this image will not be sharp after putting oil on the slide and going back to the 40x objective, it is for that reason that the 40x is called 'high dry' lens. In consequence, it is required to clean the immersion oil off the 40x objective. In general, it is required to  to remove the oil and refocus off the slide and lens immediately after oil immersion (it can be done by using an oil-soluble solvent).

Answer:

The main difference between sex cells and zygote is the chromosomal charge, where the sex cells have half of the chromosomes haploid and the zygote has the full load, is diploid, as well as the body cells.

Explanation:

Ploidy is based on the number of chromosomes found in a cell:

The reason for this difference is that the gametes go through a process of reductional division, called meiosis. They are haploid because when the gametes of the parents unite —during fertilization— they give rise to a haploid cell, the zygote.

Answer:

The simplest mechanism by which molecules can cross the plasma membrane is passive diffusion. During passive diffusion, a molecule simply dissolves in the phospholipid bilayer, diffuses across it, and then dissolves in the aqueous solution at the other side of the membrane.

Explanation:

Answer:

Diffusion is one of the processes that allows this to happen. Diffusion occurs when particles spread. They move from a region where they are in high concentration to a region where they are in low concentration.

A missense mutation is a Genetic alteration that causes the protein produced to encode a different amino acid at a specific location. Certain missense mutations change how the resulting protein functions.

While mutations always result in a change in the DNA sequence, they do not necessarily have a noticeable impact on the organism or alter the resulting protein. Since most amino acids can be encoded by two or more distinct codons, this is possible.

The ability to properly identify and characterise the majority of sequence changes makes direct DNA sequencing, in theory, the method for mutation identification with the highest degree of accuracy.

Answer:

Explanation:

Chloroplasts are specialized organelles found only in plants and some types of algae. These organelles carry out the process of photosynthesis, which turns water, carbon dioxide, and light energy into nutrients from which the plant can obtain energy. There can be over one hundred chloroplasts in certain plant cells.

Chloroplasts are disk-shaped organelles that are surrounded by a double membrane. The outer membrane forms the external surface of the chloroplast and is relatively permeable to small molecules, allowing substances entry into the organelle. The inner membrane lies just beneath the outer membrane and is less permeable to external substances.

Between the outer and inner membrane is a thin intermembrane space that is about 10-20 nanometers wide. The center of the chloroplast that is enclosed by the double membrane is a fluid matrix called the stroma (you can think of this like the cytoplasm of the chloroplast).

Within the stroma, there are many structures called thylakoids, which look like flattened disks. Thylakoids are stacked on top of one another in vascular plants in stacks called grand. Thylakoids have a high concentration of chlorophyll and carotenoids, which are pigments that capture light energy from the sun. The molecule chlorophyll is also what gives plants their green color.

I hope this helps, and Happy Holidays! :)

Answer:

Connective tissue

Explanation:

it exhibits 4 type of cells: osteoblasts, bone lining cells, osteocytes and osteoclasts.

Osmosis causes cells to shrink in size. Maintaining equilibrium between cellular and surrounding fluids is essential for life processes; however, exposure to hypertonic environments can have negative consequences on cells and cause them to shrink due to water leaving via their membrane.

Semipermeable membranes offer resistance and only allow certain types or sizes of molecules or ions into or out of cells. Such differences permit osmosis which is the migration or diffusion (spontaneous) flow 'down' gradient - from areas with lower solute concentrations to places with higher ones - for any uncharged (neutral) chemical species such as H₂O.

When two closely related birds live on separate islands and do not interbreed, the temporal isolation is occurring.

Temporal isolation is a type of reproductive isolation mechanism among sexual organisms in which the differences in the timing of critical reproductive events prevent members of closely related species.

Temporal isolation happens when two or more species reproduce at different times. For example, three species of orchid live in the same rain forest. Each species has flowers that last only one day and must be pollinated on that day to produce seeds.

One prezygotic reproductive barrier is temporal isolation. Temporal isolation means 'isolated in time,' so this is a mechanism that prevents species from mating because they breed at different times.

Explanation:

Inheritance is the key feature of the living organisms which can be best described as the transmission of DNA from parent to offspring. Thus, the correct option is C.

Inheritance is the process through which the genetic information is passed on from the parent generation to the child. This is why, the members of the same family tend to have similar kind of characteristics.

Genetic information is the DNA or chromosomes which is transferred from the parents to offspring through fertilization of gametes. Gametes are the haploid cells which contain genetic information from both the parents which combine to form an offspring with characteristics similar to both the parents.

The alternation of generations life cycle of mosses involves the production of gametes by the gametophyte, fertilization to form a zygote, growth of the zygote into the sporophyte phase, production of spores by the sporophyte, and growth of the spores into new gametophytes.

An alternation of generations in plants is a process whereby a plant alternates between two distinct phases: the gametophyte phase and the sporophyte phase.

The gametophyte phase is the dominant phase in the life cycle of mosses. It is the phase in which the plant produces gametes, which are sex cells that fuse to form a zygote,

The sporophyte phase grows out of the gametophyte and is dependent on it for nutrients. It consists of a stalk and a capsule, which contains spores.

Circuit training is a form of exercise that combines several exercises or activities performed one after the other, with minimal rest periods in between. It involves completing a series of exercises or "stations" that target different muscle groups or fitness components, such as strength, endurance, or flexibility.

Typically, circuit training involves performing a set number of repetitions or time at each station before moving on to the next station. This type of training can be customized to meet individual fitness goals and can be modified to accommodate different fitness levels or equipment availability.

Circuit training is often used as a time-efficient and effective way to improve overall fitness, increase muscular strength and endurance, and promote weight loss.
