Answer:
There are specific things that us humans experience that are caused by nature and by nurture, but there are also things that they work together on as well. I believe that gender and gender expression is fueled by both nature and nurture. An experiment was conducted in England with toddlers and adults. The adults were to watch over the toddlers and play with them. What the adults didn't know is the toddlers were dressed as the opposite sex. A little girl dressed as a male was handed "boys toys" and a boy dressed as a female was handed "girls toys". But the scientist went even further with her research and went to a zoo. Chimpanzees are our closest relatives and were the target group for the experiment. Different gendered toys were placed about and one by one monkeys began to play with the twos. However, the male chimps played with the "boys toys" and the female with the "girls toys". So it was proven quickly that while it may seem like more nurture than nature, nature does play a role in gender expression.

If the AG of a reaction was -31.45 kJoules, you would know that:
A. the products have more free energy than the reactants.
B. the reaction requires an energy input of 31.45 kJoules to proceed.
C. the reaction most likely leads to development of a more ordered system
D. the reaction is spontaneous
Answer:
The correct answer is - option D. the reaction is spontaneous. (considering it as delta G or ΔG)
Explanation:
If a chemical reaction has a negative ∆G it means the reactants have more free energy than the products due to the fact that they give off some of their free energy during the reaction.
Such reactions release free energy and therefore called exergonic reactions. These reactions are also known as spontaneous reactions as they do not require energy to take place.
Thus, the correct answer is - option D.

A strand of RNA has the sequence AUUGCGCGAA. What explanation can be made about how this strand came to be?
A. The RNA strand formed from the rearrangement of the bases in a DNA strand.
B. The RNA strand broke off from a DNA strand that had a much longer genetic code.
C. The RNA strand was transcribed from a DNA strand with the sequence TAACGCCTT.
D. The RNA strand was translated from a DNA strand that had the sequence UAACGCCUU.
A strand of RNA with the sequence "AUUGCGCGAA" has been transcribed from a DNA strand with the sequence "TAACGCCTT". Thus, the correct option is C.
What is Transcription?Transcription is the process of formation of mRNA from the DNA in the nucleus of cell. The machinery involving all the enzymes and nucleotides are present in the nucleus for the development of mRNA. mRNA is the messenger RNA which is transcribed from DNA.
The sequence of mRNA formed from the DNA in a cell is complementary to the leading strand of the DNA in which only the thymine residues are replaced by the uracil residues. Adenine base pairs with uracil and thymine residues base pairs with adenine residues. Cytosine residues base pairs with guanine residues and vice versa.
Thus, the sequence of DNA from which mRNA has been synthesized is "TAACGCCTT".
Therefore, the correct option is C.

The processes involved with reproduction and nurturing a growing zygote
require energy use beyond normal maintenance. What is the best way certain
organisms reduce the energy costs of reproduction?
A. The parents each take turns nurturing the offspring.
B. They reproduce asexually.
C. They have multiple offspring in one pregnancy.
D. They reduce their gestation period.
Answer:
B. They reproduce asexually.
Explanation:
Asexual reproduction often known as abiogenetic multiplication requires just one parent organism and results in hereditary identical progeny (similar to a new copy). Since there is no blending of genetic data required and organisms don't have to invest energy finding a mate, populaces can increment quickly because of asexual generation. Thus, with the guide of asexual generation, the energy needed in the process associated with multiplication and nurturing is diminished contrasted with sexual reproduction.

In Mendel's first set of experiments, the two forms of a trait always showed up in the ______ generation
Answer:
Mendel began his studies by growing plants that were true-breeding for a particular trait. ... In his first experiment, Mendel cross-pollinated two true-breeding plants of contrasting traits, such as purple and white flowered plants. The true-breeding parent plants are referred to as the P generation (parental generation).
Explanation:
Hope this helps a little. Pls mark brainliest.
In Mendel's first set of experiments, the two forms of a trait always showed up in the Parental generation or P generation.
What is parental generation?The parental generation is defined as the first set of parents crossed, where the genotypes of the parents will be used as the basis for predicting the genotypes of their offspring (the [tex]F_1[/tex]generation). The P generation is the beginning of Mendel's work on inheritance, or the acquisition of genetic traits by transmission from parents to offspring.
Mendel collected the seeds which is produced by the P plants that resulted from each cross and grew them, while their offspring were called the[tex]F_1,[/tex] or the first filial generation.
Thus, in Mendel's first set of experiments, the two forms of a trait always showed up in the Parental generation or P generation.

Look online and find out what each muscle group does and what at least 5 muscles do and list that information.
Flexor Group-
Peroneal Group-
Hamstring Group-
Gluteal Group-
Quadricep Group-
Extensor Group-
Sartorius Group-
Adductor Group-
Answer:
Flexor Group- group of five muscles mainly in charge of movements of forearm, hand and fingers.
Peroneal Group- these muscles play a role in the movements of the ankle joint and support of the foot.
Hamstring Group- The hamstrings are a group of muscles and their tendons at the rear of the upper leg. They include the biceps femoris, semitendinosus, and semimembranosus. The hamstrings flex the knee joint and extend the thigh to the back side of the body.
Gluteal Group- The gluteal muscles are a group of three muscles which make up the buttocks: the gluteus maximus, gluteus medius and gluteus minimus. The three muscles originate from the ilium and sacrum and insert on the femur.
Quadricep Group- The Latin translation of 'quadriceps' is 'four headed,' as the group contains four separate muscles: the vastus lateralis, vastus medialis, vastus intermedius, and the rectus femoris. Each of the vastus muscles originates on the femur bone and attaches to the patella, or kneecap.
Extensor Group- The superficial extensors of the forearm are a group of six muscles situated in the superficial posterior compartment of the forearm. These muscles include the brachioradialis, extensor carpi radialis longus, extensor carpi radialis brevis, extensor digitorum, extensor carpi ulnaris and extensor digiti minimi.
Sartorius Group- couldnt find anything
Adductor Group- The adductors are a group of muscles, as the name suggests, that primarily function to adduct the femur at the hip joint. Although they are all located somewhere along the medial side of the thigh, they originate in different places at the front of the pelvis.

A garden pea plant possesses one allele coded for yellow seed colour and one a coded for green seed colour. Which statement is true?
A green pea plant possesses one allele coded for yellow seed color and one a coded for green seed color. The true statement is the individual is heterozygous for the seed-color allele.
What are alleles?At a given genomic location, an allele is one of two or more variants of DNA sequence (a mono base or a segment of bases).
For any given genomic location where such variation exists, an individual inherits two alleles, one from each parent. If both alleles are identical, the person is similar for that allele.
Thus, the true statement is the individual is heterozygous for the seed-color allele.

Why does Dr. Giedd compare reading to the new flood of information that a child's brain must process today?
Answer:
He made this comparison because just as reading is a learned activity by the brain, so are the new flood of information that a child's brain must adapt to.
Explanation:
In describing the intricacies of the human brain, Dr. Jay Giedd talked about the brain's special ability to adapt to new behaviors as well as to multitask. Many of our ancestors lived and died without ever reading a book but humans alive today have adapted well to reading. So has the brain also adapted well to all the flood of information in our day.
The brain learns through examples and it does a good job at this. This is the more reason parents should endeavor to display good examples in the presence of their children.
