Answer:

Self-concept is the set of ideas that make up the image that each person has about himself, that is, it is the opinion that an individual forges about himself. That sentence carries a certain value judgment. Self-concept: set of elements that a person uses to describe himself. Self-motivation is giving the reasons, the drive, the enthusiasm and the interest that provoke a specific action or a certain behavior. Volunteer is the person who, by his own choice, dedicates part of a part of his time to solidary, altruistic action, without receiving remuneration in return. The stage that comes after childhood and that ranges from puberty to the full development of the body is known as adolescence. Self-image is the value we have in relation to ourselves.

Explanation:

Self-concept: set of elements that a person uses to describe himself. The ability to motivate yourself is what is known as self-motivation. This is an important skill, as it encourages people to continue progressing even in the face of setbacks, to seize opportunities and to show commitment to what they want to achieve. Volunteer is that person who joins an organization in a free way to help altruistically in various social activities. When we speak of self-image we refer to the image that our subconscious has of ourselves. Adolescence is understood as the period of human development after childhood and before adulthood, in which the biological, sexual, social and psychological changes necessary to form a socially mature individual and physically prepared for reproduction take place.

PLEASE HELP!!! Give two forms of evidence for evolution that can be found in the fossil record (where animals have changed from
Pavel [41]

Answer:

Forms of fossil records can inlude the carcasses of animals and the structure of plants. These records can compare the advancements of creatures over a long period of time.

Explanation:

The further an animal or plant is burried underneath the soil, it is most likely that it lived much longer ago than a layer above it. The theory of evolution suggests that animals are always changing and adapting to their surroundings. For instance, millions of years ago, a dog like mamal existed but over time they grew accustomed to the water, developing fins flippers and eventually developed features similar to what we expect in whales today.

Plants, on the other hand, may have been much larger than the size they are today due to the excess of oxygen present in the atmosphere. Therefore, when they are fossilized scientists can realize that plants have come a long way in the tree of evolution.

Is the heme molecule attached to hemoglobin during the primary level or tertiary level of organization?
djyliett [7]

Answer:

Tertiary.

Explanation:

Primary structure of proteins refers to the order of amino acids that make up the protein. The heme is an nonprotein non-amino acid, so it is not involved at this stage.

Tertiary structure of proteins is the overall 3-D folding of the protein (it comes after secondary, which involves folding into a repeated pattern). The heme bonds to its correct position on the hemoglobin during this stage and helps in correct folding.

In maize (corn) plants, a dominant allele I inhibits kernel color, while the recessive allele i permits color when homozygous. A
EleoNora [17]

Answer:

Phenotype ratio= 12 colorless : 3 purple : 1 red

Genotype ratio= 1:2:1:2:4:2:1:2:1

Explanation:

According to the given information, the dominant allele "I" is epistatic to P and p alleles and presence of "I" inhibits the expression of both "P" and "p" alleles.

A cross between two heterozygous plants for both locus would give the F2 progeny in 12 colorless: 3 purple: 1 red ratio.

Here, the F2 genotype with "I-G" and "I-gg" would produce colorless kernels while the ones with "ii-G-" would exhibit purple colored kernels. The F2 genotype "iigg" would beak red kernels.

Hence, the phenotype ratio= 12 colorless : 3 purple : 1 red

Genotype ratio would be same as for the mendelian dihybrid cross= 1 IIPP: 2 IIPp :1 IIpp: 2 IiPP :4 IiPp: 2 Iipp: 1 iiPP :2 iiPp: 1 iipp
