Answer 1

Answer:

1aNeon

b. positive charge.

c. As atomic number is equal to no. of protons and no. of electron and atomic number 10 element is Neon.

Positive charge as it have lost one of it's electron.

Atomic number = no. of protons = no. of electron and since electron can be shared loose or gain to develop charge it have loose on electron.

2a. 4 protons

b. 2 electrons

c. In question 2(a) the atomic number of Be is 4 so it would have four protons.

And as for question (b) it is said it have 2 charge which means positive charge would mean that it have lost 2 electrons and is left with 2 electrons which fulfill it's duplet configuration.

Why do bases have to be read in groups of 3?

Answers

Divisible by three" is important because the cell reads a gene in groups of three bases. Each group of three bases corresponds to one of 20 different amino acids used to build a protein. If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly.

When one gram of liquid water at its boiling point is changed into water vapor

Answers

Answer:

Water needs 40.65 kJ/mole of energy.

Explanation:

One gram of liquid water changed into water vapor at its boiling point, energy is required called the heat of vaporization. Water has a heat of vaporization of 40.65 kJ/mol. Hydrogen bonding is present between water molecules so to break this hydrogen bond, heat energy is required. This heat energy is different for different liquids, water needs 40.65 kJ/mole of energy to break the bond and change into vapors.

Self-report inventories and projective tests are examples of personality assessments,
Please select the best answer from the choices provided
True or false

Answers

I think the answer is true but I’m not sure.

It is true that Self-report inventories and projective tests are examples of personality assessments.

What are Self-report inventories?

An individual fills out a survey or questionnaire for a self-report inventory, a sort of psychological examination, with or without the assistance of the researcher.

Self-report questionnaires frequently pose direct questions on a person's preferences, morals, symptoms, actions, and personality types.

A projective test is a personality test used in psychology that asks subjects to respond to ambiguous stimuli, ostensibly to discover hidden emotions and internal conflicts that the subject then projects onto the exam.

A projective test asks participants to freely respond to stimuli intended to disclose personal needs, sentiments, or personality traits as opposed to a self-report inventory, which asks predefined questions intended to represent a specific characteristic.

Thus, the given statement is true.

The family is causing less fertilizer to enter the water.
The family is causing less trees to be cut down.

Answers

I know this because  if the family was using less renwwable resourses it wouldn't be a problem. And if the family was causing less fertlizer to enter the water, that would be helping. So would causing fewer trees to be cut down. So it is all about the process of elimination! Hope I could help

A family decides to use their bicycles to get to the mall on weekends instead of driving a car, and the family is helping the environment by using fewer non-renewable resources, which is in option B.

What are non-renewable resources?

Using bicycles instead of driving cars is an environmentally friendly choice because it helps reduce the consumption of non-renewable resources, such as fossil fuels, as fossil fuels are a limited resource that takes millions of years to form and their use contributes to air pollution and greenhouse gas emissions, which are major contributors to climate change. In addition to the environmental benefits, cycling can also have positive health impacts. Regular cycling can help improve cardiovascular health and reduce the risk of chronic diseases such as obesity and diabetes.

Hence, the family is helping the environment by using fewer non-renewable resources, which is in Option B.

When you a red bird mates with a white bird mate all the offspring have pink feathers. What can best explain this observation?

Answers

Answer:

Incomplete dominance

Explanation:

Incomplete dominance is a type of non-mendelian inheritance pattern in which one allele of a gene is not dominant or recessive to the other allele, hence, both alleles combine to form a third intermediate phenotype, which is a blending of both parental phenotypes.

In this case, a red bird (RR) mates with a white bird (WW) to produce offsprings that have pink feathers (RW). This shows that the allele for red coloration is incompletely dominant to the allele for white coloration, hence, both combines to produce a PINK (RW) intermediate phenotype. This portrays incomplete dominance.

When executing these plays, every individual must work together in a specific role; this teaches children how to work together. Since sports are based on competition, participants also learn how to lose gracefully and develop a sense of fair play. Children who participate in sports develop a stronger sense of self-esteem and responsibility than children who favor other activities.
