Which are examples of harmful mutations? Check all that apply. One that causes a person to have a light patch of hair color one that changes a mouse's eye shape but not its eyesight O one that allows a moth to blend into its environment one that reduces a bean plant's ability to make food one that increases the plants susceptibility to disease

Answers

Answer 1

Answer:

one that reduces a bean plant's ability to make food

one that increases the plants susceptibility to disease

Explanation:

Genetic mutation refers to the changes in the arrangement of the bases that make up a gene. This sudden change may have positive or negative consequences for the individual specie.

Some genetic mutations actually alter a gene's sequence of bases but do not alter the function of the particular protein that the gene in question makes.

The two options chosen in the answer shows situations in which a genetic mutation causes harm to the organism involved.

Answer 2

moles in 9.01x10^23 molecules water

Answers

Answer:

The answer is 1.50 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{9.01 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{9.01}{6.02} \\ = 1.496677740...[/tex]

A. How many molecules of sugar are in 20.5 g of sugar?

Answers

Answer:

By definition, one mole (one gram molecular weight) of any substance, contains Avogadro’s number of particles; atoms if you are discussing an element, or molecules if a compound. Avogadro’s number has been determined by several methods, all of the accepted values lie within a range of +-1% about the value of 6.022045 x 10^23/gm. That is a large number, in this case approximately; 602,204,500,000,000,000,000,000 molecules of glucose.

Which of these elements has an electron configuration of [Kr]5s2?
barium

calcium

rubidium

strontium

Answers

Strontium has an electron configuration of [Kr]5s²

Further explanation  

In an atom there are levels of energy in the shell and sub shell  

This energy level is expressed in the form of electron configurations.  

Writing electron configurations starts from the lowest to the highest sub-shell energy level. There are 4 sub-shells in the shell of an atom, namely s, p, d and f. The maximum number of electrons for each sub shell is  

s: 2 electrons  

p: 6 electrons  

d: 10 electrons and  

f: 14 electrons  

From an electron configuration of [Kr]5s² can be concluded :

element is in period 5 (5 = shell)element is group 2(valence electron =2 and block s) has atomic number 38 (Kr = 36 + 2(valence elektron from 5s²)

If we look at the periodic system, the elements that meet the requirements in question are Strontium (Sr)

Human body uses the energy provided from food digestion. Endothermic or exothermic?

Answers

Answer:

Endothermic

Explanation:

Exo is outside so exothermic would be outside the body

The carbohydrates are break down into glucose. Then glucose combines with oxygen in the cells and provides energy. Hence, digestion is an exothermic process.

What is an exothermic process ?

Food digestion produces heat. This happens as a result of the organism releasing heat during meal digestion. A process that releases heat is exothermic.

Heat is released during an exothermic reaction, raising the temperature of the immediate environment. The environment is cooled through an endothermic process that absorbs heat.

Glucose is created by the breakdown of these carbs. In the cells of our body, this glucose interacts with oxygen to produce energy. So, the process of digesting is exothermic.

Chemical processes involved in food digestion disassemble large food molecules into smaller, more manageable "building block" components.

Thus, Human body uses the energy provided from food digestion is exothermic process.

What colors are the fireworks in the photo? How do you
think the matter and energy of fireworks of different colors are similar and
different?

Answers

Answer:

Shortly after, the electron will fall back down to a lower energy level, releasing energy in the form of light. Therein lies the key to colorful fireworks!

The matter and energy of fireworks simply rely on the flow of electrons from the ground stage to the excitatory stage.

What is Matter?

Matter may be defined as any sort of substance that is constructed of numerous types of particles that occupy physical space and possess inertia. In simple words, matter may be characterized as anything which occupies space and has mass.

When the electrons move from the ground stage to the excitatory stage, they require a significant amount of energy in any form. But when they fall back to the ground stage from the excitatory stage, they liberates energy.

The same principle is applied in the colorful observation of fireworks. The stored energy is released and different colors of fireworks become visible.

Therefore, the matter and energy of fireworks simply rely on the flow of electrons from the ground stage to the excitatory stage and vice-versa.

pure sodium and chlorine are extremely dangerous, but when combined the result in substance that we use every day. How do you think the properties of sodium and chlorine change when they are combined to make sodium chloride?

Answers

Answer:

Explanation:

chlorine has 7 valence electrons while sodium has 1. on their own, they are very reactive elements. a full valence electron shell has 8 electrons, so when elements combine and have 8 electrons in their outer shell, they are not reactive. when sodium and chlorine are combined to form sodium chloride (table salt), it is no longer dangerous. the number of valence electrons changes its reactivity and how it combines.

The properties of sodium and chlorine change when they are combined to make sodium chloride should be explained below.

Information regarding chlorine:

chlorine comprises of 7 valence electrons while on other hand, sodium has 1.  A full valence electron shell contains the 8 electrons, so when elements combine and have 8 electrons in their outer shell, they are not reactive.
