Answer:

The punnet square in this question is unclear. The punnet square has been attached as an image.

Based on the punnet square, the answer is C. Two long, two short

Explanation:

This question involves a single gene coding for needle length in cactus plant. The allele for long needle (L) is dominant over the allele for short needle (l).

According to the question, two cacti were crossed with genotypes Ll and ll respectively. The following allelic combinations of gametes will be produced by each parent

Ll- L and l

ll- l and l

Using these gametes in a punnet square (as seen in the image below), four possible offsprings with genotypes: Ll and ll will be produced in a 1:1 proportion.

Ll offsprings will be phenotypically long-needled while ll offsprings will be phenotypically short-needled. Hence, two long needle offsprings and two short needle offsprings will be produced in this cross.

Answer:

They were spotless and soundless

Explanation:

The control group is used as a reference to compare the result obtained from the experimental group.

The control group differ from the experimental group in the 2005 peacock butterfly experiment in ways such as the control groups of butterflies having their spots covered with paints. A small part of the peacock’s wings were also removed to prevent them from making sound.

This validates them being spotless and soundless

Answer:

The neutrophil is the first line of defense, it is called as PMN OR POLYMORPHONUCLEAR NEUTROPHIL, this cell is said to be the first line of defense for the first to reach the area of ​​infection or in the area of ​​trauma, this upon reaching that area (where it is attracted by defense chemomodulators) it recognizes the bacteria or the foreign body as an antigen, since these do not present the cellular histocompatibility complex of our organism, by recognizing it as an antigen, this cell can detect that it is not something typical of our body but something new that was inoculated, is how this phagocyte to the bacteria and induces its own programmed cell death.

In an injury or infection, the purulent collection is not only debris and pathogenic microorganisms, but they are dead cell bodies of PMNs that induce their own cell death with the battery inside to be able to inhibit its advance in our body, when this phenomenon passes the PMN it is called a peach.

Explanation:

In the event that no antibodies are present, it would not change much if it is the first time that the bacteria enters our body since the formation of antibodies by the lymphocyte cell line occurs as the last stage of immunity (neutrophils appear first, then the antigen presenting cells and finally the lymphocyte lineage in charge of making immunological memory with antibodies).

The PMN are guided more than anything by the humoral factor of the immune response, but the proinflammatory factor like cytokines or leukins, but not by the antibodies, that is why he wrote this process of bacterial assimilation in the response.

Answer:

The kinetochore of the chromosomes

Explanation:

What could be damaged that is hindering the spindle fibers from attaching to the chromosomes are the kinetochores of the chromosomes.

At the metaphase stage of the cell division, the chromosomes align at the equator of the cell and the spindle fibers engage each chromosome at a region known as the kinetochore.

The kinetochore is made up of complex proteins and lies around the centromere region of the chromosome. The microtubules of the spindle fibers attach to this region during the metaphase stage.

If the kinetochore is damaged, it means the spindle fiber will not be able to attach to the chromosome.

Answer:In many ways, meiosis is a lot like mitosis. The cell goes through similar stages and uses similar strategies to organize and separate chromosomes. In meiosis, however, the cell has a more complex task. It still needs to separate sister chromatids (the two halves of a duplicated chromosome), as in mitosis. But it must also separate homologous chromosomes, the similar but nonidentical chromosome pairs an organism receives from its two parents.

Explanation:Mitosis(Opens in a new window)(Opens in a new window) is used for almost all of your body’s cell division needs. It adds new cells during development and replaces old and worn-out cells throughout your life. The goal of mitosis is to produce daughter cells that are genetically identical to their mothers, with not a single chromosome more or less.

Meiosis, on the other hand, is used for just one purpose in the human body: the production of gametes—sex cells, or sperm and eggs. Its goal is to make daughter cells with exactly half as many chromosomes as the starting cell.

To put that another way, meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes. In humans, the haploid cells made in meiosis are sperm and eggs. When a sperm and an egg join in fertilization, the two haploid sets of chromosomes form a complete diploid set: a new genome.

Answer:

When one is nervous activates the sympathetic system and the irrigation towards the cardiac and muscular zone is increased, increases the arterial tension and the respiratory rate.

That is why the blood or blood volume is dispersed in these organs to be able to render efficiently in a moment of stress or flight for the human.

When we have sexual intercourse and there is sexual excitement, a large part of the blood volume goes to the reproductive organs to be able to irrigate the area and produce said excitement, if we are stressed in an alert situation, it will be harmed by the priority body to irrigate the main areas like heart and muscle.

Explanation:

It is important to clarify that the physiological stress in humans is a normal situation, thanks to the presence of cortisol and it is what keeps us active, but if it increases due to anxiety or overwork, psychological problems, etc., it will no longer be physiological due to that is in excess.

Thus, sexual arousal will also be affected by the psychological impotence generated by excess mental stress outside the vascular pattern.

Scientists studying the effects of warming on boreal forests which change the biome.

Explanation:

The main effect of warming on boreal forests is to change the biome because the plants and animals will not tolerate the increased temperature which occcurs due to climate change so the plants and animals disappeared from the boreal forests and change its biome. The animals migrated to other suitable environment where they continue its growth and increase their population. If climate projections are correct, the biome of this forest go to those places where the environment is suitable.

Answer:

A replacement of a letter with different letter would indicate a missense mutation. (eg. GGA would become something like GCA and it would make something completely different).

Explanation:

A missense mutation is when the RNA replicates the instructions wrong from the DNA. When RNA is transcribed to make amino acids, it will make a completely different amino acid rather than the one that is needed/blueprinted. For example, if the sequence was AAG in the RNA (Derived from TTC DNA), it would create Lys amino acid. However, if the RNA sequence was AGG (Derived from abnormal TCC DNA), it would make Arg amino acid, which is different.

Athletes who train short distances and explosive moments of extreme metabolic anaerobiosis have a higher percentage of fast fibers in the muscular structure of skeletal muscles, that is, in the muscles that achieve and carry out locomotion.

Some researchers also argue that men have a predisposition to have more fast fibers than women, since these are predominantly slow fibers.

Rapid muscle fibers to the leg muscle, generating more powerful contractions with less presence of oxygen and greater lactic acidification in the metabolism of the energy currency.

Explanation:

Fast and slow fibers are two different types of fibers, these are usually trained according to the histology or physiology of each athlete.

Those with the highest amount of fast fibers will train and perform better in high-power physical activities, that is, for short distances with little demand for oxygen.

Answer:

1. TATA Box

Explanation:

TFIID, also called transcription factor II D, is a Transcription Factor that interacts with the minor groove of the TATA box. The TATA element is a core promoter component present in genes of eukaryotic organisms, which is formed by the consensus sequence TATA(A/T)A(A/T).  

TFIID is involved in the first stage of the transcription process, during the formation of the pre-initiation complex. TFIID contains a TATA-binding subunit and a complex of associated factors (TBP-associated factors) that interact with specific RNA polymerases, for example, by interacting with the RNA polymerase II (RNAP II) during transcription of the messenger RNA (mRNA).

Answer:

A. Average plant height increases with an increase in the concentration of sodium phosphate until the plants reach a maximum possible height.

Explanation:

The graph in the attachment section portrays the average height of plants (cm) on the y-axis plotted against the concentration of sodium phoshate (mg/L) on the x-axis. Based on the observation of the result in the graph, an increase in the concentration of phosphate caused an increase in the average plant height (as depicted by the upward-sloping line).

However, the plant's average height didn't go beyond 35cm despite an increase in concentration of phosphate. This is because the plants has reached a maximum possible height i.e. a height climax. Hence, they cannot grow taller than 35cm no matter the amount of external nutrients (sodium phosphate) supplied.

Therefore, the noticeable trend that can be used to make a conclusion is that average plant height increases with an increase in the concentration of sodium phosphate until the plants reach a maximum possible height.

Brain is a complex structure and needs analgamation of various methods to get a clearer picture.

One method is cavalder studies where brains of dead person is compared. For instance , Einstien brain was compared with ordinary people brain. The ratio of glia cells to neuron was hypothesised to be higher in high IQ person such as Einstien. However , this cannot be ascertained as only one special brain was available.

Lession studies help us identify the problem associated with a lession in a particular area and conclude the function of specific region of brain.for example , during stroke the is clot in frontal lobe that leads to epileptic ceasure sometimes.

Drawback of these method is that brain is not active. So new method of EEG electro encephelogram which measure electrical signals if each neuron. It measures brain activity when brain is active.

the EEG can provide information about the general patterns of electrical activity within the brain, and although the EEG allows the researcher to see these changes quickly as they occur in real time, the electrodes must be placed on the surface of the skull and each electrode measures brain waves from large areas of the brain. As a result, EEGs do not provide a very clear picture of the structure of the brain. A still images of brain cannot be obtained by placing electrodes to measure electrical signal.

But MRI techniques exist to provide more specific brain images. Functional magnetic resonance imaging uses a scan method utilising magnetic field to create an image of brain in each activity area.

Thus all methods combined can help in study of brain and associated activities more profoundly and effectively.
