A woman who can roll her tongue (presumably dominant) is married to a man who cannot. Two of their four children can roll their tongues and two cannot. If A = roll tongue and a = cannot roll tongue, then what is the genotype of the parents?

Answer:

The fossils are able to give scientists clues about the type of organism that lived in an ancient environment.

Explanation:

Fossils are able to give scientists clues about the type of organism that lived in an ancient environment. That's because fossils are records of living things that were alive hundreds and millions of years ago.

When we talk about fossils we immediately think of bones, but the fossils can be taken, feces, leaves, roots, hair, among other factors of a living organism, which was trapped in rocks for many years, kept conserved and can be studied and evaluated.

Answer:

x=8, B

Explanation:

3(x+1)+6=33

3x+9=33

3x=24

x=8

Answer: Gene

Explanation:

Mutation can be defined as the change in the single base pair of the DNA. Each and every trait inside an eukaryotic organism body is controlled by the help of the gene.

Pie bald is also a trait controlled by the genes in the body. Pie bald can be defined as a pattern of unpigmented spots on the pigmented background of scale, feather and hair.

Example: A pie bald black and white dog is a black dog with white spots on it.

Both plants and cyanobacteria use water, sunlight, and carbon dioxide in photosynthesis. The correct answer is "a".

Both plants and cyanobacteria utilize water, sunlight, and carbon dioxide in the process of photosynthesis.

Photosynthesis is the biochemical process by which organisms convert light energy into chemical energy in the form of glucose.

Water:

• Both plants and cyanobacteria absorb water from their environment through their roots or cell surfaces.
• Water molecules are split during photosynthesis, providing a source of electrons for the light-dependent reactions and releasing oxygen as a byproduct.

Sunlight:

• Sunlight is essential for photosynthesis as it provides the energy necessary to power the process.
• Chlorophyll, the pigment found in plants and cyanobacteria, captures light energy and initiates the series of chemical reactions involved in photosynthesis.

Carbon dioxide:

• Plants and cyanobacteria take in carbon dioxide from the atmosphere through small openings called stomata or through their cell surfaces.
• Carbon dioxide serves as the carbon source for the synthesis of organic molecules during photosynthesis.

Thus, the correct option is a.

Final answer:

Human females produce egg cells through a process called oogenesis. This process involves stages of meiosis and maturation. Only a small number of egg cells will actually mature and be released during a woman's reproductive years.

Explanation:

Human females produce egg cells through a process called oogenesis. Oogenesis begins during fetal development, where billions of egg cells form in the ovaries. However, only a small number of these cells will actually mature and be released during a woman's reproductive years.

Oogenesis is a complex and regulated process that involves several stages. The primary stage is called meiosis, where the chromosomes in the developing egg cell undergo DNA replication and cell division to create haploid cells with half the number of chromosomes. These haploid cells are then referred to as secondary oocytes. The secondary oocytes undergo further maturation and, when fertilized by a sperm cell, can develop into a human embryo.
