Answer:

The personal items should be off the table, and the lab materials should be placed neatly away from the edge of the table.

Explanation:

It is given that Maribel goes to the lab with her backpack and she is given the lab materials to be used inside the lab to perform her experiment.

Now Maribel in the lab before doing her experiment must keep the personal items like her backpack off the working table and the lab materials are should be kept away from the edge of the table otherwise it might fall accidentally and hurt her.

One needs to be very careful while in the laboratory. One should follow the safety procedures to remain safe and also ensure safety of others. Being unsafe and disorganize can hurt others and can cause harm to others. There are various equipment and chemical in the lab. Therefore one should be careful while working in the lab.

Image result for what is The recessive gene for blood typing

Because A is dominant, that means your mother could carry a hidden O. If she does then when she gets pregnant, each child has a 50% chance of getting her dominant A and a 50% chance of getting her hidden, recessive O. If the child gets the O from mom and an O from dad, he or she will have an O blood type.

diffusion and osmosis

Explanation:

lipid_ soluble substance

through lipid baleyer

through protein channel

Transported proteins carry small substances like water, amino acids, and charged ions. One to fifteen angstroms is the range in molecule size that can pass through the membrane. The easier it is for a molecule to move across the cell membrane, the smaller it is.

All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.

Small molecules or ions can traverse the cell membrane passively without the cell providing any energy. The three basic types of passive transport are osmosis, assisted diffusion, and diffusion.

Gases like oxygen and carbon dioxide, as well as small hydrophobic compounds, quickly traverse membranes. Water and ethanol are examples of small polar molecules that can move across membranes, though more slowly.

Thus, The easier it is for a molecule to move across the cell membrane, the smaller it is.

Answer:

it takes 50 min

Explanation:

20 is twice of ten so if it take 25 min to cook ten then it is 50 min to cook 20.

Work for it:

10 x 2 = 20

10 eggs=10 min

25x2=50

Answer:

it takes 50 minutes to cook 20 eggs

Explanation:

ok first you have to see how long it takes 1 egg to cook so 25/10=2.5minute an egg then u multiply 2.5 x 20=50

Answer:

The no. of heterozygous carriers = 0.0392

Explanation:

From the given information:

The incidence of this recessive disorder i.e. q² = 1/2500

q² = 0.0004

q = 0.02

From Hardy Weinberg's Equilibrium.

p + q = 1; &

p² + 2pq + q² = 1

∴

p + 0.02 = 1

p = 1 - 0.02

p = 0.98

So, the numbers of heterozygous carrier 2pq is:

= 2 × 0.98 × 0.02

= 0.0392

Answer:

eight million

Explanation:

Eight million different ways can the 23 homologous pairs in a human germ cell.

One of a pair of chromosomes with the same gene sequence, locations, chromosomal length, and centromere placement is referred to as a homologous chromosome. One paternal and one maternal chromosome make up a homologous pair.

A somatic cell of a human has a total of 46 chromosomes in its nucleus. The father inherits half of them (22 autosomes Plus X or Y chromosome), while the mother inherits the other half (22 autosomes + X chromosome).

A female typically has 23 homologous chromosomes, compared to a male's 22. This is due to the fact that men' X and Y sex chromosomes are not identical. During meiosis, homologous chromosomal pairing is crucial.

Therefore, Eight million different ways can the 23 homologous pairs in a human germ cell.

Answer:

There are 1600 atoms when organism just died.

Explanation:

The statement is incorrect. The correct statement is:

If a sample known to be about 11,460 years old and has 400 carbon 14 atoms. How many atoms are in the sample when organisms just died?

The amount of atoms associated with radioactive isotopes decreases exponentially in time by means of the following formula:

[tex]n(t) = n_{o}\cdot e^{-\frac{t}{\tau} }[/tex] (1)

Where:

[tex]n_{o}[/tex] - Initial amount of atoms.

[tex]n(t)[/tex] - Current amount of atoms.

[tex]t[/tex] - Time, measured in years.

[tex]\tau[/tex] - Time constant, measured in years.

In addition, the time constant can be calculated in terms of the half-life of the radioactive isotope ([tex]t_{1/2}[/tex]), measured in years:

[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (2)

If we know that [tex]t_{1/2} = 5,730\,yr[/tex], [tex]t = 11,460\,yr[/tex] and [tex]n(11,460\,yr) = 400[/tex], then the initial amount of atoms is:

[tex]n_{o} = \frac{n(t)}{e^{-\frac{t}{\tau} }}[/tex]

[tex]\tau = \frac{5,730\,yr}{\ln 2}[/tex]

[tex]\tau \approx 8,266.643\,yr[/tex]

[tex]n_{o} = \frac{400}{e^{-\frac{11,460\,yr}{8,266.643\,yr} }}[/tex]

[tex]n_{o} \approx 1600[/tex]

There are 1600 atoms when organism just died.

Answer: Mendel's research lead to several conclusions about the traits and its passing through generations. The two of the conclusion are different forms of a gene account for variation in the inherited traits and some alleles are dominant over others for a given trait.

Explanation

George Mendel was a famous biologist. His research was on genes and traits. His experiment shows how genes gets transferred from parents to offspring. Also he stated about the behavior and dominance and recessive nature of that alleles.

He also gives the possibility of dominance of a trait over other trait. The different forms of gene are responsible for various types of inherited traits in an organism.
