1-Brown eyes (B) are dominant to blue eyes (b). Straight hair (H) is dominant to curly hair (h). Free earlobes (E) are dominant to attached earlobes (e). If individual one who has the genotype BbHhEe is crossed with individual two who has the genotype bbhhEe, what is the probability that their offspring has brown eyes, straight hair, and attached earlobes?(I asked last time but I didn't get a serious answer, please make your answers as one percentage.)
Answer:
The correct answer would be - 1/16 or 6.25% is the probability that their offspring has brown eyes, straight hair, and attached earlobes
Explanation:
In this question, it is given that-
1. Brown eyes (B) are dominant to blue eyes (b)
2. Straight hair (H) is dominant to curly hair (h)
3. Free earlobes (E) are dominant to attached earlobes (e)
Now the cross between BbHhEe (Brown eyes-straight hair-free earlobe) with bbhhEe (blue eyes-curly hair-free earlobe) takes place.
Gametes will be -
BbHhEe - BHE, BhE, Bhe, BHe, bHE, bHe, bhE, bhe
bbhhEe - bhE, bhe
cross would be -
BHE BhE Bhe BHe bHE bHe bhE bhe
bhE BbHhEE BbhhEE BbhhEe BbHhEe bbHhEE bbHhEe bbhhEE bbhhEe
bhe BbHhEe BbhhEe Bbhhee BbHhee bbHhEe bbHhEe bbhhEe bbhhee
By the Punnett cross, we get only one out of 16 offspring with brown eyes, straight hair, and attached earlobes
Thus, the correct answer would be - 1/16 or 6.25% is the probability that their offspring has brown eyes, straight hair, and attached earlobes

In order to measure the absorption spectrum of CoCl2, you need to dilute the stock solution to 0.32 M. What volume of the stock solution (0.8 M concentration) and water should be mixed to make a 10 mL solution of 0.32 M?
Explanation:
Volume of stock solution needed
= 10mL * (0.32M/0.8M)
= 10mL * (4/10) = 4mL.
Volume of water needed
= 10mL - Volume of stock solution
= 10mL - 4mL = 6mL.
The volume of water needed in this case will be equal to 6 ml.
What is the stock solution?To make a stock solution, weigh out the proper amount of a pure solid or measure out the proper amount of a pure liquid, put it in the right flask, and then dilute it to the desired volume. Depending on the intended concentration unit, many methods can be used to measure the reagent.
For instance, to make a solution with specified molarity, you weigh out the proper mass of the reagent, mix it with some solvent, and then add enough liquid to make the necessary volume. You measure out the right amount of solute and add enough solvent to get the right total volume to create a solution where the solute concentration is expressed as a volume percent.
A highly concentrated stock solution is frequently diluted to create solutions. The stock solution is moved to a new vessel and produced to a new volume at a known volume.
Here,
The volume of stock solution needed
= 10mL × (0.32M/0.8M)
= 10mL × (4/10) = 4mL.
The volume of water needed
= 10mL - Volume of stock solution
= 10mL - 4mL = 6mL.
Therefore the volume of water needed here is equal to 6 ml.

Which statement is the most accurate regarding the first stage of photosynthesis?(1 point)
Sugar molecules like glucose are formed, and this is a light-independent stage.
Radiant energy is converted into chemical energy, and this is a light-dependent stage.
Radiant energy is converted into chemical energy, and this is a light-independent stage.
Sugar molecules like glucose are formed, and this is a light-dependent stage
The final products of fotosynthesis are carbohydrates, ATP, NADPH, and oxygen is released. During the firt stage of photosynthesis, radiant energy is converted into chemical energy, and this is a light-dependent stage.
Stages of Photosynthesis
Photosynthesis involves two stages: light-dependent and light-independent reactions.
During light-dependent reactions, oxygen is released, while ATP and NADPH are produced. Both of them are used during light-independent reactions.Light-independent reaction is known as the Calvin cycle, and it takes place in the stroma. Sugars or carbohydrates are synthesizedLight-Dependent reaction
Chlorophyll molecule in Photosystem II captures luminous energy from the sun. The pigments absorb light, exciting the electrons, which get in a higher energy level. Excited electrons leave photosystem II and move to photosystem I along the electron transport chain. When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules. Photosystem I absorbs more luminous energy that drives the electrons to another electron acceptor, from where they get transported again and used to produce NADPH molecules. When electrons are sent from Photosystem I, they are replaced by new electrons coming from photosystem II through the transport chain. As electrons go through the transport chain, their released energy is used to produce ATP molecules.

Hypersecretion of growth hormone after normal growth has ceased may cause
acromegaly
achondroplastic dwarfism
pituitary dwarfism
gigantism
Answer:
gigantism
Explanation:
The growth hormone is responsible for stimulating normal growth in humans or in other words, stimulating growth at a normal pace. To do this, the growth hormone must be released in optimal quantities, however, an hypersecretion i.e. excessive release of the hormone will cause a fast and uncontrollable growth in certain regions of their body or the whole.
This abnormal excessive growth caused by an excessive release of the growth hormone is called GIGANTISM. Gigantism occurs mostly in children at their growing phase.

Describe what might happen to an amino group or a carboxyl group of an amino acid, if that amino acid is placed into water.
Answer:
Amino acids are the monomers that makeup proteins. This amino acid is unionized, but if it were placed in water at pH 7, its amino group would pick up another hydrogen and a positive charge, and the hydroxyl in its carboxyl group would lose and hydrogen and gain a negative charge.
Explanation:
Each amino acid has the same fundamental structure, which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. In the aqueous environment of the cell, both the amino group and the carboxyl group are ionized under physiological conditions, and so have the structures -NH3+ and -COO–, respectively. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. This R group, or side chain, gives each amino acid protein-specific characteristics, including size, polarity, and pH.
