During the Human Genome Project, scientists created a gene map showing the relative location of each known gene on every human c

hromosome. This map led to the discovery that the human genome is made up of about how many genes?

Arlecino [84]2 years ago
3 0

Answer:

Approximately 20,500 genes

Explanation:

The Human Genome Project (HGP) was a 13-year international research effort aimed at determining the entire DNA sequence of the human genome. The HGP was launched in 1990 and completed in April 2013. This project helped to identify and physically map all the genes of the human genome. The sequence obtained from the HGP has been a very useful point of reference in order to identify and characterize mutations associated with genetic disorders. The HGP predicted approximately 20,500 genes (each of them produces an average of three proteins), which are distributed in the 23 pairs of chromosomes in the cells of our body.

Which of the following accurately describes the role of energy in cellular respiration?
zmey [24]

Answer:

The correct answer is option energy is a product.

Explanation:

Cellular respiration is a process in which oxidation of food or glucose takes place to produce energy. This process proceeds in four processes: glycolysis, oxidative carboxylation, Krebs cycle and electron transport chain.

All of this process produces energy in the form of ATP or energy equivalents like NADH and FADH₂.  

1. Glycolysis produces- 2 ATP, 2 NADH,  

2. Oxidative carboxylation produces- 2 NADH,  

3. Krebs cycle produces- 2 ATP, 6 NADH AND 2 FADH₂ and  

4. Electron transport chain produces at last- 24 ATP from these reducing equivalents.

Thus, option energy is a product is a correct option.

How does natural selection lead to the evolution of a species?
serious [3.7K]

Answer:

One of these is natural selection, which is a process that increases the frequency of advantageous gene variants, called alleles, in a population. Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation.

As the bear enters hibernation, its metabolic processes such as body temperature, heart rate, and respiratory rate are reduced. But bears do not lower the body temperature as much as once thought. Their hibernation temperature is around 88 degrees and waking temperature is 100 degrees F. This relatively high sleeping temperature allows bears to become fully alert if aroused, perhaps to enable the bear to protect itself from predators and other dangers without unnecessarily taxing their energy reserves. Over the course of a hibernating season it is thought that bears use approximately 4 thousand calories a day, which results in a weight loss of about 20 percent of it body weight by spring.

One g of fecal matter was suspended in 99 ml saline solution (tube 1). After mixing gently but thoroughly, one ml from tube 1 wa
malfutka [58]

Answer: the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3

Explanation:

We know that; Gram negative bacteria looks  pale reddish in color under a light microscope from Gram staining.

therefore

There are 30 red bacterial colonies counted.

1 mL of from tube 1 was removed and added to tube with 99 mL saline (tube 2) dilution is 1/100.

transferred volume  into the plate is 1 mL.

Now, we have to determine the cfu/g Gram-negative bacteria in the fecal sample

Formula to calculate CFU/g bacteria in fecal sample is expressed as;

C = n/(s×d )

where C is concentration (CFU/g) , n is number of colonies , s is volume transferred to plate , d is dilution factor.

so we substitute

C = 30 / ((1/100) × 1)

C = 30 / 0.01

C = 3000

C = 3.0 × 10^3

THERFERE, the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3
