Answer:

is the first, and most general, mechanism of protection against pathogens

Explanation:

Innate or natural immunity is one of the two types of immunity an organism can possess (the other being; acquired immunity). Innate immunity is the FIRST defensive response of an organism against pathogenic attacks. The acquired immune system is only activated when the innate immune system has been penetrated or surmounted.

For example, the skin, mucus secretion, inflammation etc. are all natural or innate defenses against foreign invaders. Therefore, according to this question, innate immunity the first, and most general i.e. commonly used, mechanism of protection against pathogens.

Answer:

Bones increase in length because of growth plates in the bones called epiphyses. As puberty progresses, the growth plates mature, and at the end of puberty they fuse and stop growing. ... After the growth plates fuse, there is no more increase in height, and we all then shrink gradually as we get older.

A possible hypothesis for this situation is that tank 1 contains denitrifying bacteria, tank 2 contains nitrite nitrifying bacteria, and tank 3 contains ammonia nitrifying bacteria.

A hypothesis, which is a common term used in experiments refers to a possible explanation for the results or phenomenon observed. In this case, a hypothesis needs to focus on the type of bacteria that are present in each of the tanks.

This means that to write a hypothesis we need to relate the type of bacteria to each of the tanks.

Hi. Unfortunately, you didn't show the answer options, which makes it impossible for me to answer your question. However, I'm going to give you some general information about seeds that can help you find the right answer. Hope this helps you.

Seeds are structures responsible for plant proliferation. They exist only in gymnosperms and angiosperms and are absent in bryophytes and pteridophytes. All seeds are formed in the ovary of flowers as a result of the plant fertilization process.

All seeds are formed by three structures known as integument, nutrient and embryo. The embryo is what gives rise to another plant, which will grow after the seed is planted and germinates. Nutrients will be responsible for meeting the needs of the new plant during the beginning of its development. The integument, in turn, has the function of protecting the embryo.

Answer: 4. Abnormal production of chain of Hemoglobin

Explanation:

Anemia is a condition where the cells in the body do not get enough oxygen because the red blood cells needed to transport them are either too little or are dysfunctional.

One way the red blood cells can be dysfunctional is when they have an abnormal type of hemoglobin. Hemoglobin is necessary in red blood cells to enable to transportation of oxygen and if it is dysfunctional, oxygen will have problems being transported which would lead to anemia.

Answer:

habitat loss, over-harvesting, and introduction of exotic species

Explanation:

The way that people have altered natural environments to create room for farms or to collect natural resources has posed the greatest harm to biodiversity yet, but as climate change intensifies, it will have a rising influence on ecosystems.

The term "biodiversity loss" describes the decline in biodiversity brought on by the extinction or relocating of species. Some people might not consider the extinction of a certain species to be significant, especially if it is not a charismatic species such as the Bengal tiger or the humpback dolphin.

However, according to estimates from scientists, the present pace of species extinctions is several times higher than the background, or average, rate seen throughout Earth's history. Within our lifetimes, this amounts to the extinction of tens of thousands of species.

The breakdown of ecosystems is anticipated to have drastic repercussions on human welfare. Because of the intricate relationships between species, a loss of biodiversity may have a ripple effect on ecosystems.

One species' extinction, for instance, may result in the extermination of another. Scientists evaluate which species are in danger of extinction as well as the state of the ecosystems to gauge the loss of biodiversity.

Therefore, the way that people have altered natural environments to create room for farms or to collect natural resources has posed the greatest harm to biodiversity yet, but as climate change intensifies, it will have a rising influence on ecosystems.

Answer:

Consider two solutions of different sodium concentrations separated by a selectively permeable membrane. The net movement of water across the membrane will be from the area of high sodium concentration to the area of low sodium concentration

Explanation:

In this process, only water molecules can pass through the selectively permeable membrane. As the solution has different concentrations of solute, the water molecules will move from the more concentrated solution to the less concentrated solution. The process is called osmosis and is completed when both solutions have the same concentration.

Field guides

Explanation:

Various species of plants and nimals exists some of which bears very similar resemblance but for some key differences which may be unknown to learners or observers. A field guide gives a description of plants and animals, stating key physical differences between similar plants and animals. This helps learners distinguish between the related organisms. Field guides are most useful when applied to habitats where a range of similar organisms have been spotted and the field guide is then taken to such habitat to physically identify each different plant or animal.

Answer:

Spring 2

Explanation:

A mutation is any change in the sequence of DNA because of any reason such as deletion, insertion, etc. To determine the mutation in a DNA molecule changed the structure of a specific protein scientists should know the normal sequence of bases that code for the protein.

A mutation is a random change in the DNA sequence either due to insertion, deletion, or substitution.

By mutating a gene's code for making a protein, a variant can leads to a protein's improper functioning or to not being produced at all.

Scientists must mandatorily determine the normal base sequence of the protein code before investigating the mutation in the DNA sequence for a particular protein.

Thus, the correct option is A.

Answer:

Explanation:

During prophase I,  chromosomes get condensed. Each of the chromosomes gets in pair with its homologous one. They do so to make the crossing-over possible, a stage where they interchange their parts → 2n

During metaphase I, each of the homologous pairs is driven to the equatorial plane, where they randomly line up → 2n

During anaphase I, occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair → 2n  

In telophase I, half of the chromosomes are already in one of the poles, while the other half is on the other pole. Each group of chromosomes has now half the number of the original cell. The nuclear membrane forms again in each pole → n

Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.

The two new cells are ready for meiosis II.

Mitosis and Meiosis are the two types of cell division, in which the genetic material is replicated and transferred to the daughter cells.

The stages of meiosis in which chromosomes are diploid are prophase, metaphase, and anaphase. The haploid chromosomes are observed in telophase.

Meiosis is a reduction division in which genetic material is halved, such that a reduction in which diploid parent cells give rise to haploid daughter cells.

The stages of meiosis at which chromosomes are diploid and haploid are:

1. Prophase I is the first phase of meiosis I. The chromosomes are condensed and pair with the homologous chromosomes.

2. Metaphase I is characterized by the homologous pairs aligning at the equatorial plane.

3. Anaphase I is the independent separation of chromosomes, which migrate to opposite poles.

4. Telophase I is represented by the separation of chromosomes having a haploid number of chromosomes, which are now segregated into daughter cells.

Therefore, telophase I am the phase in which chromosomes are present in haploid numbers.
