True or false:Winds are named by the direction they come from.


Answer:

Drag and gravity.

Explanation:

When planes push the air aside using the area they cover, they are said to have a lot of drag or resistance when they move through the air. Paper airplanes, due to their lightweight and thin build, have very little drag, allowing them to weave through the air without too much resistance. Gravity also bears down on the paper, albeit with minimal effect due to its light constitution.

Answer:

The way paper airplanes can fly is that it has to have aerodynamics, drag and gravity, and thrust and lift. Drag and gravity happens when the plane pushes the air aside using the area they cover. Thrust and lift helps the paper planes have extended flights.

D.  Warmed air sinks  is not a normal convection cycle outcome

Explanation:

Warm air is buoyant and rises.  Cold air is dense and sinks.

Think of fog in the air.  Fog forms in low/cool areas, as the sun comes out and warms up the atmosphere the upper atmosphere, heat flows to cold so upper atmosphere air displaces the fog.

Space heating, the steam or hot water radiators are placed along the floor typically causing convection of warm air to rise up over windows and cold walls, breaking up cold air drafts.

Half will have red flowers and half will have white flowers (option c).

In camellia plants, flower color is controlled by a single gene with codominant alleles. In this case, one parent plant has red flowers (R), while the other parent plant has white flowers (WW).

When two organisms with codominant alleles are crossed, both alleles are expressed equally in the offspring. Therefore, in this cross, the offspring will inherit one allele for red flowers (R) from the red-flowered parent and one allele for white flowers (W) from the white-flowered parent.

The possible combinations of alleles that the offspring can inherit are RW and RW.

When the alleles RW and RW combine, the resulting genotypes are RR (red-flowered) and RW (pink-flowered). However, since the allele for white flowers (W) is recessive to the allele for red flowers (R), the plants with the RW genotype will exhibit the dominant red flower phenotype.

Therefore, half of the offspring will have the RR genotype and display red flowers, while the other half will have the RW genotype and also display red flowers. None of the offspring will have the WW genotype, so there won't be any white flowers.

Hence, the expected phenotypes of the offspring of this cross are that half will have red flowers and half will have white flowers. Thus, the correct option is c.

Explanation:

The law of superposition states that fossils found in the uppermost layers, i.e., layer A, are more recent than those found in the other layers, so option A is correct for the youngest fossil.

When the environment changes due to climatic changes, animals or plants remain under the rocks, leaving their imprints or hard parts of their bodies, which are later studied to learn about ancestors. The fossils that are present in the lowermost rock layers are the oldest, while the uppermost layer is the youngest as it is newly formed.

As a result, the law of superposition states that fossils found in the uppermost layers, i.e., layer A, are more recent than those found in the other layers, so option A is correct for the youngest fossil.

An atom is described as a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.

Protons and neutrons make up the core nucleus of an atom, which is encircled by an electron cloud. In relation to the size of the atom as a whole, the nucleus is exceedingly small.

As a result, the electrons surrounding the nucleus are the primary target of interactions when particles or even light pass through an atom. The majority of the atom's remaining space, which includes the nucleus, is vacant.

About the question:

I failed to find the result of the PCR / electrophoresis. However, I will try to explain when to still consider a sample, and when to exclude it.

Answer:

Probably elephants 1, 2, 4, and 6 exposed a pattern of lines that differed in most alleles from the ivory´s pattern. So they were considered to be different and, hence, excluded. However, elephants 3 and 5 only were different in one allele, which might be due to the amplification failure. In these last situations, the experiment must be run again, and include many markers.

Explanation:

The genetic profile is the series of alleles, characteristic of each individual, concerning a series of DNA fragments.

Once genetic profiles are obtained by using PCR/electrophoresis, they must be subjected to interpretation. The researcher must compare profiles to find concordance between individuals or the lack of it.

In the exposed example, probably we have a profile of the ivory sample, and we need to find out to what individual or population it belongs to. So we need to compare the pattern of bands of the different lanes with the ivory´s pattern of bands.

In resumed terms, if the ivory´s patterns completely match with another lane pattern, then this is the individuals or population to whom it belongs the ivory. However, if they do not match, we need to exclude this individual.

But this is not as easy as it looks like. Sometimes it is difficult to interpret the results because bands are not so clear, and sometimes there are failures during amplification, as said before in the statement of the problem.

In these situations, what you need to do is look for the lanes that match the most with the ivory one and discard those that differ the most. These last patterns probably belong to a different animal or population, that why they can be excluded. Individuals suspected of being the same as the individual understudy or belonging to the same population, must be subducted to a repetition of the study. Also, the use of several markers in the study increases the matches chances.

So, in the exposed example, if the amplification fails in one allele, elephants 3 and 5 could be a match to the ivory sample, probably because all the other alleles do match. You can only exclude them if, after the experiment repetition, the involved allele is still different. On the other hand, you can eliminate the elephants 1, 2, 4, and 6 because their pattern bands are significantly different from the ivory´s patterns, so you do not even need to repeat the experiment.

In C. elegans, cell-cell signalling specifies vulval cell fates, causing the Pnp, cells to adopt primary, secondary or tertiary fates. The primary will increase with rate of ras function, decrease with loss of one kinase and no change in  ras (gf) plus loss of kinase. The tertiary will have no effect during loss of one kinase but increase with gain of ras function.

(A) The predicted effect of the ras (gf) mutation is that, mutation in each of the cell will have the fate as follows. The gain of ras function will increase in primary and tertiary. More than three of the six VPCs differentiate into vulva cells.

(B) The predicted effect of the loss of one kinase mutation is that, mutation in each of the cell will have the fate as follows. The loss of kinase will have no effect on tertiary and primary will decrease. One of the two daughter cells of P6.p (primary cell) fails to divide further and differentiate into vulval tissue whereas the two adjacent VPCs are normal, resulting in two small ventral protrusions. The defective P6.p daughter cell can be at either the left or right side of the normal daughter cell.

(C) The predicted effect of the ras function plus loss of one kinase mutation is that, mutation in each of the cell will have the fate as follows. The ras function plus loss of one kinase will have no effect on both primary and tertiary. The vulva development is same as in wild type.

Homeostasis can also occur at pH and nutrition levels, for instance. Particles travel through a process called diffusion from a region where they are more concentrated to one where they are less concentrated. Diffusion is employed to maintain a cell's equilibrium concentration when homeostasis is under danger.

Diffusion is the overall net movement of anything from a higher concentration to a lower concentration. A gradient in the Gibbs free energy or chemical potential drives diffusion.

Molecules go through the cell membrane due to diffusion. In order to balance the internal conditions of the cell with the external environment, molecules of a substance migrate over a gradient of concentration.

Thus,  Diffusion is employed to maintain a cell's equilibrium concentration when homeostasis is under danger.

The organism described that can cause illness and death in humans, reproduces asexually, and is among the simplest of living things, is a bacterium.

Bacteria are single-celled microorganisms that can be found in various environments, including soil. They are characterized by their simplicity of structure and lack of a nucleus or membrane-bound organelles.

Certain species of bacteria are pathogenic and have the ability to cause diseases in humans. Examples include bacteria like Escherichia coli (E. coli), Salmonella, and Staphylococcus aureus.

These bacteria can enter the human body through various means, such as contaminated food or water, and can cause a range of illnesses, from mild to severe, and even life-threatening conditions.

Bacteria have the ability to reproduce asexually through a process called binary fission. In this process, a single bacterium divides into two identical daughter cells, allowing for rapid multiplication of the population.

It is important to note that while bacteria can be harmful, many bacteria are beneficial or have neutral effects on humans and play crucial roles in various ecological processes and human health.
