When a heterozygous tall (Tt) crosses with a homozygous tall (TT), 50% of the offspring are homozygous tall and 50% are heterozygous tall.

When the same alleles of a gene are found on both homologous chromosomes, a cell is said to be homozygous for that gene.

A person who has two copies of the allele that codes for the dominant characteristic is said to be homozygous-dominant for that trait. This allele, which is sometimes referred to as the "dominant allele," is typically denoted by the uppercase version of the letter used for the associated recessive characteristic (such as "P" for the dominant allele producing purple flowers in pea plants). An organism's genotype is symbolized by a doubling of the trait's symbol, such as "PP," when it is homozygously dominant for that trait.

When a diploid organism's cells have two distinct alleles of a gene—one wild-type allele and one mutant allele—they are said to be heterozygous at that gene locus.

50% of the progeny is going to have the Ee genotype after both people mate.

Let us take the genotype for having no ear lobes be e.

Similarly, the genotype for having ear lobes is going to be E.

This means that whoever is homozygous for no ear lobes will have the genotype ee.

Whoever is homozygous for ear lobes will have the EE genotype.

After a person with the ee genotype mates with a person having the EE genotype, their offspring will have the genotypes - (EE, Ee, Ee, ee)

From this, we can conclude that 50% of the progeny is going to have the Ee genotype.

Since many nutrient cycles are interconnected, modifications to one cycle will have an impact on another. This implies that the quantity of nitrogen present in an ecosystem has a direct impact on changes in the amount of carbon dioxide fixed.

The movement of substance and energy between living things and the ecosystem's non-living components happens through a mechanism called the nutrient cycle. This happens because once plants and animals ingest nutrients from the soil, they die and decompose, releasing those nutrients back into the ecosystem.

The mechanism whereby an enveloped virus leaves a host cell is called   budding.  option 3)

Virus can reproduce only within a host cell, this cycle of infection begins with the attachment, where the virus attaches to a specific receptor site on the host cell, after this comes the entry, in the case of enveloped virus, the envelope can fuse directly with the cell membrane to enter the cell, they can also enter through endocytosis.

After entering the cell the virus initiates a replication  and assembly mechanism depending on its genome, finally, the last stage of viral replication is the release or egress of the new virions produced in the host organism, some viruses can be released when the host cell dies, but some can leave infected cells by budding through the membrane without directly killing the cell.

The following data description techniques are NOT appropriate for visualizing an attribute 'Hair length' that has values 'Short/Medium/Long':

Pie chart and Histogram. Explanation:

A pie chart is a visual representation of data that highlights relative sizes of a dataset. It is a circular statistical graph. It can display one or more than one dataset. The main use of a pie chart is to display the proportionate size of each slice in relation to the whole.

However, for the given attribute 'Hair length' that has values 'Short/Medium/Long', a pie chart is not an appropriate data visualization technique as it cannot display ranges of data. It can only display the relative proportion of a particular category on the whole.

It is not suitable for representing data with only a few distinct values because it won't be able to accurately represent the different values in each category. In summary, Pie chart and Histogram are not appropriate data visualization techniques for the given attribute 'Hair length' that has values 'Short/Medium/Long'.

Human bodies, like those of other mammals, adhere to general rules of proportions that govern their overall structure and dimensions. These rules ensure a harmonious and functional design, allowing for efficient movement and biological functions.

One fundamental principle of proportionality in the human body is the concept of symmetry. A balanced symmetry is evident in various aspects, such as the arrangement of paired organs (e.g., eyes, ears) and the bilateral symmetry of the skeletal system. This symmetry provides stability and enhances coordinated movement.

Additionally, the human body follows the principle of proportional scaling. This means that different body parts have a consistent relationship to one another in terms of size and length. For example, the length of the upper arm is typically about twice the length of the forearm. Similarly, the overall height of an individual is often around eight times the length of their head.

These general rules of proportionality in human bodies are not absolute, as there can be individual variations and cultural influences. However, understanding these principles provides valuable insights for various fields, such as anatomy, art, and design.

Explanation:

The purpose of DNA extraction liquid is to break open cells and dissolve cellular membranes, proteins, and other cellular components in order to release DNA from the cell. This is an essential step in DNA extraction procedures, as DNA is tightly packed within the cell and needs to be isolated and purified for further analysis.

There are many different types of DNA extraction liquids that can be used depending on the type of sample and the downstream application. Commonly used extraction liquids include phenol-chloroform, ethanol, and various commercial kits that utilize a variety of chemical agents and protocols.

The DNA extraction liquid typically contains a combination of reagents that help to disrupt the cell membrane and denature cellular proteins, allowing the DNA to be released and separated from other cellular components. These reagents can include detergents, salts, enzymes, and organic solvents. After the DNA has been released from the cell, it can be further purified using various methods, such as precipitation or column-based purification, depending on the specific application.

In summary, the purpose of DNA extraction liquid is to break open cells and release the DNA for further analysis. It is a critical step in many molecular biology and biotechnology applications, including genetic research, diagnosis of genetic diseases, and forensic analysis.

Explanation:

a. If the loci controlling banding and color in Cepaea nemoralis are linked with no crossing over, the results of the test cross will be 100% banded, yellow snails because the recessive alleles for both traits will always be inherited together.

Without recombination, all the F1 gametes will contain only these two allelic combinations, in equal proportions. Therefore, the F2 testcross progeny will be ½ banded, yellow, and ½ unbanded, brown.

b. If the loci assort independently, the results of the test cross will be a 1:1:1:1 ratio of phenotypes: 25% banded, yellow snails; 25% unbanded, yellow snails; 25% banded, brown snails; and 25% unbanded, brown snails.

c. If the loci are linked and 20 m.u. apart, the results of the test cross will be a mixture of parental and recombinant phenotypes. The recombination frequency is 20%, so each of the two classes of recombinant progeny must be 10%. The expected ratio would be:

Answer:

90

Explanation:

Not all the energy is passed from one level of the food chain to the next. About 90 per cent of energy may be lost as heat (released during respiration), through movement, or in materials that the consumer does not digest. The energy stored in undigested materials can be transferred to decomposers.

Answer:

Energy can be lost in a multitude of ways in a food chain. 90% of energy is usually lost either in the form of heat, through movement while using energy, or materials that are not entirely consumed by the consumer.

Explanation:

Only about 10% of energy is retained after a consumer eats a lower level on the food chain. Further explained, heat is released during respiration, which is essentially energy being lost.

Animals also have metabolism and growth, which require energy of their own. So, not all energy in a food chain can be retained for the animals to use.

The amino acids would be most similar to the ingredients used in the recipe.

When the mRNA moves out of the nucleus, it then gives the instructions (the genetic sequence) to someone else, which is tRNA. During translation, the tRNA and mRNA complex reads the genetic sequence and then binds required amino acids, sequentially. Thus, the combined amino acid chain forms the desired protein.
