Answer:
A conserved set of cyclin-dependent protein kinases (Cdks) initiate or regulate events through phosphorylation of intracellular proteins, thus controlling cell cycle progression, terminal differentiation, and apoptosis. ...
Explanation:
The cell cycle regulators are cyclins, CDKs, and CDK inhibitors as well as some of their substrates, interaction partners, and upstream regulators.
What is a cell?
The smallest unit of life is a cell. There are biomolecules in it. Every living thing is composed of several cell units. Different sorts of creatures contain various types of cells.
Prokaryotic cells are the most basic types of cells; they are only seen in unicellular organisms, do not engage in cell division, and lack real cell organelles and a nucleus, instead having DNA coiling up in the cytoplasm.
Eukaryotic cells are higher cells that contain cell organelles and have the capacity to carry out a variety of intricate tasks required by big organisms.
Thus, Cell signaling is a method of communication between or within cells, and a change in a cell's activity is conveyed as a signal that may set off a chain of events so that the body can respond appropriately.

What is true about two different cell types in the body?
Answer:
Option B
Explanation:
In cell differentiation, the objective is to differentiate cells based on their functions and the organs they are going to form. In this exercise, the cells need to get on and off to define the type of the cell and its function. Hence options A, C is important for cell differentiation. Information from DNA is transferred to mRNA for cell differentiation; hence option D is also correct. While option B has no role in cell differentiation loss of DNA segment could cause mutation i.e. deletion.
Hence, option B is the correct answer

In cherry tomatoes, red color (R) is dominant to yellow color (r). If two heterozygous plants are crossed, what percentage of the offspring will be yellow?
Answer:
50
Explanation:
If you cross two heterozygous tomato plants, you get four base genotypes of (Respectively,) RR, Rr, Rr, and rr. That makes your percentage A. 50%.
Explain h0mozygous and heter0zygous?If a dominant red fruit (RR) plant is crossed with a recessive over yellow fruit (rr), then the phenotype will be red fruit and the genotype Rr. It is a case of complete dominance.
In diploid organisms (2n), an individual is homo-zygous when it carries two copies of the same gene variant (i.e., the same allele).
Moreover, an individual is heter0zygous when it carries two different alleles for the same gene locus.
In complete dominance, the dominant allele completely masks the expression of the recessive allele in heter0zygous individuals.
Thus, That makes your percentage A. 50%.

What are the three types of forests age and structure?
Answer:
Tropical rain forests grow around the equator in South America, Africa, and Southeast Asia, The temperature is stable year-round, around 27°C (60° Fahrenheit). As you can tell from the name, it rains a lot in these forests. Most tropical forests receive at least 200 cm (80 inches) of rain in a year. Tropical forests generally have a rainy and dry season. Temperate forests occur in the next latitude ring, in North America, northeastern Asia, and Europe, temperature ranges from -30 to 30°C (-22 to 86 F) and the forests receive 75-150 cm (30-60 in) of precipitation per year,

__________ is a method of studying complex systems by reducing the components that are studied (e.g. studying cells in culture and using those results to understand what is going on in a complex disease).
Select one:
a.
emergent properties
b.
systems biology
c.
genomics
d.
reductionism
Answer: A.
Explanation: "An emergent property is a property which a collection or complex system has, but which the individual members do not have. In biology, for example, heart is made of heart cells, heart cells on their own don't have the property of pumping blood. You will need the whole heart to be able to pump blood."
Explanation for the incorrect answer:
"Systems biology is the computational and mathematical analysis and modeling of complex biological systems. It is a biology-based interdisciplinary field of study that focuses on complex interactions within biological systems, using a holistic approach to biological research. "
what is the shape of the bacteria thiobacillus
Answer:
this bacteria has a rod shaped form
Answer:
rod-shaped
Explanation:
Bacteria in the genus Thiobacilli are classified within the order Pseudomonadales. They are small, rod-shaped cells (0.5 by 1–3.0 µm) which may be motile or nonmotile. Motility is due to a single polar flagellum. Bergey's Manual (1957) lists nine species, most of which are aerobic.
What are some negative impacts of having this life cycle that might have contributed to a decline in the dragonfly population?
Answer:
Dragonflies are important for our environment.
Explanation:
Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.
Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water. The dragon flies rely on the aquatic ecosystems all through their life. Thus dragonflies are an important indicators of the environment and water quality.
Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.
State the function of Bowman's capsule and glomerulus.
➜ Bowman's capsule and glomerulus have semipermeable walls.
The glomerulus, is a tuft of capillaries contained in Bowman's capsule.The water and dissolved substances (wastes and useful) are filtered into the Bowman's capsule and from here they are filtered into the tubule.Thus, both the structures act as filtering apparatus.When a car slams on breaks, a book in the seat of the car slides forward. What terms describes why that happens?
Answer: Newton's first law which states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
