The finches may have speciated from the  Galápagos finch and now occupy different habitats.

The term speciation has to do with a type of evolution that gives rise to new organisms from existing ones. It is common in the world today. These ne organisms all tend to coexist with each but may not be on the same habitat.

For instance, the finches may have speciated from the  Galápagos finch and now occupy different habitats.

The event which takes place during normal fertilization is zygote formation.

The major event which is characteristic of fertilization is zygote, otherwise termed cell formation in which case, the zygote is capable of undergoing cell division to form a new living cell. The fusion of two gametes necessary for fertilization kick-starts several reactions in the egg.

Answer: Red blood cells placed in a solution with higher water concentration compared to their contents will gain water by osmosis that will then swell up and then burst.

Explanation:

Osmosis causes red blood cells to release water when they are exposed to sodium chloride solutions that are more concentrated than their internal environment (hypertonic solutions).

Hemolysis is the term for this process. In an attempt to balance the solute concentration, water is pulled out of the cells by the high concentration of sodium chloride outside the cells, creating an osmotic gradient. The result is that the cells shrink and may eventually rupture or burst. Lack of water reduces internal pressure and destabilizes cell membranes, causing red blood cells to burst.

This phenomenon underscores how important it is to maintain the correct balance of solute concentrations to protect the structural and functional integrity of red blood cells.

Haploid and diploid are terms that represent the sets of the chromosome of an organism.

The thread-like components known as chromosomes are found in the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA).

When an organism's cells only have one set of chromosomes, the organism is said to be a haploid. All organisms that reproduce sexually are diploid (having two sets of chromosomes, one from each parent). Only the egg and sperm cells in humans are haploid.

The number of chromosomes found inside a cell's nucleus is known as the diploid chromosomal number. The symbol for this number is 2n. Each organism has a different one. In contrast to sex cells, somatic cells are diploid.

The sucrose move in source to sieve by active transport.

Active transport is a type of transport in which the cell expends energy to move solutes against their concentration gradients. The sodium-potassium pump is an example of active transport. Active transport differs from passive transport in that the cell does not expend energy.

In this case, the sucrose moves from companion cells into source to sieve elements by active transport. This reduces the water potential of the source to sieve element  by osmosis, which increases the hydrostatic pressure.

Answer:

Genetic diversity is a good principle for secure development because it is critical for a population to adapt to changing environments. It helps maintain the health of a population.

Explanation:

Genetic Diversity refers to the range of different inherited traits within a species. In a species with high genetic diversity, there would be many individuals with a wide variety of different traits.

Mutations are important to genetic diversity because it creates a new DNA sequence for a particular gene, creating a new allele. This is important because including alleles that are diverse may be valuable in resisting diseases, pests, and other stresses

Genetic diversity is a good principle for secure development because it ensures the chances of adaptation in living organisms with respect to changing environmental conditions.

Genetic diversity may be defined as the total number of genetic characteristics in the genetic makeup of a species. It serves as a way for populations to adapt to changing environments. It facilitates the survival of particular species.

A lack of diversity may have a negative impact on security. This can be understood by the example that if there were not many variables seen in the Darwin finches in the Galapagos islands, more birds feel the scarcity of food and due to this, they have died and become extinct from nature.

Therefore, with more genetic variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment.

Answer:trait encoding for short plant structure to reduce transport of water

Explanation:The Sahara Desert is a zone which receives very low or no precipitation. This region receives maximum of sunlight not received by any other biome. The soil is typically sand which is highly porous and lacks essential growth nutrients necessary for plant growth. The plants grown around Sahara Desert are xerophytic plants. These plants undergoes several adaptations in order to prevent loss of water through transpiration. Trait encoding for short plant structure to reduce transport of water is a xerophytic adaptation.
