The outcome of the cross between a homozygous dominance yellow seed plant (GG) and a homozygous recessive green seed plant (gg) can be represented using a Punnett square.

A Punnett square is a diagram that shows the possible offspring genotypes from a cross between two parents. In this cross, the alleles from each parent are placed along the top and the left side of the square, and the resulting offspring genotypes are placed in the boxes within the square.

In this case, the offspring will all be heterozygous (Gg) and have yellow seeds because the dominance allele (G) masks the expression of the recessive allele (g). Therefore, the cross between a homozygous dominance yellow seed plant and a homozygous recessive green seed plant will result in all offspring having yellow seeds, even though they carry both yellow and green alleles.

To detect the presence of non-culturable prokaryotes in an environmental sample using microscopy methods such as fluorescence microscopy and polymerase chain reaction (PCR), the first step is:

Fluorescence Microscopy: Label the prokaryotes in the sample with a fluorescence tag. This can be done by adding a fluorescent antibody specific to the prokaryote or using a fluorescently labeled oligonucleotide probe that specifically binds to the prokaryote's DNA. The sample is then viewed under a fluorescence microscope to detect the presence of the labeled prokaryotes.

Polymerase Chain Reaction (PCR): To detect the presence of prokaryotes that cannot be visualized using fluorescence microscopy, PCR can be used. This involves amplifying a small piece of the prokaryote's DNA and then detecting it using gel electrophoresis, qPCR, or other methods. To do this, the environmental sample must first be lysed to release the prokaryotes' DNA, which is then purified and used as template for the PCR reaction.

Overall, these methods allow for the detection of the presence of non-culturable prokaryotes in environmental samples, even if they cannot be grown in a laboratory culture.

The structure that would be found in both gram-positive and gram-negative cells is peptidoglycan (option B)

The peptidoglycan cell wall that encloses gram-negative bacteria is surrounded by a lipopolysaccharide-rich outer membrane. Gram-positive bacteria have much thicker layers of peptidoglycan than Gram-negative bacteria, which have an outer membrane.

Both Gram-positive and Gram-negative bacteria have peptidoglycans in their cell walls, which give the cells their distinctive shapes and mechanical protection. Peptidoglycans are only found in prokaryotic organisms and are made up of peptide chains that are either minimally cross-linked in Gram-negative bacteria or strongly cross-linked with bridges in Gram-positive bacteria (such as Staphylococcus aureus) (e.g., Escherichia coli).

The genotype in F1 generation would be produced as RrWW, RrWw and rrww and the phenotype would be red eyes with long wings in three organisms and one phenotype with brown eyes and dumpy wings.

RR are dominant to rr eyes. WW wings are dominant to ww wings. The cross takes places between true bleeding fly with red eyes & dumpy wings, i.e. RRww, to a true-breeding fly with brown eyes & long wings, i.e. rrWW. The phenotypes here would be produces in a ratio 3:1. And, three types of genotypes would be produced in F1 generation.

Refer the image attached for the reference of a Punnett square for the dihybrid cross of the given traits. The phenotypic ratio here would be produced as 9:3:3:1. The cross described here contains the inheritance of two traits, i.e., the eye color and the size of the wings. Hence, this is a dihybrid cross.

Answer:

Structure is the answer

Your body's tissues may be repaired and built up using protein. It triggers metabolic processes, preserves fluid and pH equilibrium, and supports a robust immune system.

A surplus of peptides is frequently excreted, but a surplus of protein is generally stored as fat. Over time, this might lead to weight gain, notably if you try to increase your protein intake while overeating.

A serious protein deficiency can impair children's development, cause fatty liver and skin, cause emphysema, and exacerbate infections. Although a true deficit is rare in wealthy countries, a low intake can cause muscle atrophy and an elevated risk of fractures.

Answer: D- Consumer (or Heterotroph)

Hope this helps :)

Explanation:

Answer:

B. Evolutionary change is likely to increase when competition increases. This is because when competition increases, organisms must adapt and evolve in order to survive. Natural selection will favor those organisms who are best suited to the environment and this will drive evolutionary change.

Plants require at least 17 essential nutrients for growth, and these can be divided into two categories: macronutrients and micronutrients.

Macronutrients are those required by plants in relatively large amounts, and they include:

These macronutrients are involved in various essential processes such as the formation of chlorophyll, protein synthesis, energy transfer, and cell division.

Micronutrients, on the other hand, are required in much smaller amounts but are still vital for plant growth and health. These include:

Micronutrients play important roles in plant metabolism and growth, including processes such as photosynthesis, hormone synthesis, and cell division.

In general , forces that include van der Waals forces, hydrogen bonding, will helps the atoms to repel from each other. Hence, When you push down upon a block, you are applying an external force to it , that will cause the atoms at the surface of the block to compress slightly.

The compression will then results to an increase in the contact force between the block and the table, that as a result will  prevents the block from moving downward further.
