1. Make a prediction of how self-control impacted the GPA of the students in the study and explain WHY you think so. 2. Then answer one of these questions: What helps you control yourself?
What makes you feel out of control?
What makes you fearful?
What helps you feel calm?
Answer:
Explanation:
1. A study conducted by Tangney, Baumeister, and Boone, indicates that self-control not only could predict GPA, but also better adjustment, better interpersonal, secure attachment, and more optimal emotional responses.
2. Start by slowing your thinking down. Take slow deep breaths. Take yourself to a quiet place. By learning how to recognize our inner emotions and thoughts, name them, and let them pass through us, we can practice more self-control, which also helps build greater agency.
11. How has our misguided, or inappropriate, use of antibiotics led to the development of organisms like
MRSA and VRSA?
Answer:
1. use of the wrong antibiotic
2. use of insufficient concentration of the right antibiotic
Explanation:
MRSA means Methicillin-resistant staphylococcus aureus
VRSA means Vancomycin-resistant Staphylococcus aureus
These are resistant forms of the bacteria Staphylococcus aureus to the antibiotics mentioned.
Bacterial resistance to antibiotics occurs when bacteria develop mechanisms that protect them against the effects of previously effective antibiotics.
Misguided and inappropriate use of antibiotics results in resistance, and they mainly occur as a result of two activities:
1. Use of wrong antibiotics: antibiotics are chosen using a microbiological technique called 'sensitivity testing', to determine which antibiotic is effective against a bacterium. However, when antibiotics are taken without proper sensitivity testing, the bacteria develop resistance against such antibiotics.
2. Use of inadequate concentration of the right antibiotic: This involves using less than the minimum inhibitory of minimum bactericidal concentration of an antibiotic against a bacteria. In this case, the organism has ample time to evolve in the presence of the antibiotic, hence the occurrence of resistance.

What kind of genetic disorder is represented in the pedigree?
Answer:
an autosomal recessive disorder
Explanation:
Autosomal recessive disorders are inherited diseases caused by the presence of two copies (alleles) of an abnormal gene, thereby only homo-zygous recessive individuals are affected by this type of disease. In consequence, although both parents don't express the disease, they can be carriers and pass this recessive disorder to their offspring who express the disease. In this case, the pedigree shows that heterozygous parents are not affected but they are carriers of the recessive allele for this disease, thereby some offspring express the trait. The black circle (female) and the black square (male) indicate affected individuals in the pedigree chart. Since both parents are heterozygous, 1/4 (25%) of all offspring would be expected to have the autosomal recessive disorder.

When farmers want two desirable traits in cows, they often breed individuals that have those traits in the hopes that the offspring will have both desirable traits. What is this practice called?
Variation
Adaptation
Natural selection
Artificial selection
Answer:
artificial selection
Explanation:
When farmers want two desirable traits in cows, they often breed individuals that have those traits in the hopes that the offspring will have both desirable traits. The practice is called Artificial selection.
What is Artificial selection?Artificial selection is the process of identifying desirable qualities in plants and animals and then taking action to strengthen and pass those traits on to succeeding generations.
Artificial selection operates in a similar manner to natural selection, with the exception that in natural selection, these judgments are made by nature without human intervention.
Natural selection, sometimes summed up by the adage "survival of the fittest," is predicated on the following ideas: In the natural world, organisms give birth to more children than they can keep alive and reproduce.
Therefore, When farmers want two desirable traits in cows, they often breed individuals that have those traits in the hopes that the offspring will have both desirable traits. The practice is called Artificial selection.

Which type of tumor, benign or malignant, causes more damage to the body?
Answer:
A malignant tumor is more dangerous because it can grow quickly. It may grow into or spread to other parts of the brain or to the spinal cord.
Explanation:
Tumors can be benign (noncancerous) or malignant (cancerous). Benign tumors tend to grow slowly and do not spread. Malignant tumors can grow rapidly, invade and destroy nearby normal tissues, and spread throughout the body.

Is the following statement true or false?
Evolutionary fitness means that an organism can reproduce successfully.
O True
O False
Answer:
TRUE
Explanation:
To an evolutionary biologist, fitness simply means reproductive success and reflects how well an organism is adapted to its environment. ... Organisms which are better suited to their environment will reproduce more and so increase the proportion of the population with their traits.
Describe what happens to the egg during the menstrual cycle on day 14. _______________________
Answer:Ok so A few days before Day 14, your estrogen levels peak and cause a sharp rise in the level of luteinizing hormone (LH). LH causes the mature follicle to burst and release an egg from the ovary, called ovulation, on Day 14.At about day 14 in the menstrual cycle, a sudden surge in luteinizing hormone causes the ovary to release its egg. The egg begins its five-day travel through a narrow, hollow structure called the fallopian tube to the uterus. hope this helps have a nice night ❤️❤️❤️
Explanation:
Answer: Because However, during days 10 to 14, only one of the developing follicles forms a fully mature egg. At about day 14 in the menstrual cycle, a sudden surge in luteinizing hormone causes the ovary to release its egg. The egg begins its five-day travel through a narrow, hollow structure called the fallopian tube to the uterus. The egg travels down the fallopian tubes. If pregnancy doesn't occur, the egg is reabsorbed into the body. Levels of oestrogen and progesterone fall, and the womb lining comes away and leaves the body as a period (the menstrual flow). The time from the release of an egg to the start of a period is around 10 to 16 days.
Explanation:
Match the following hormones to their functions.
1.)luteinizing hormone (LH)
2.)growth hormone (GH)
3.)oxytocin (OT)
4.)insulin
5.)antidiuretic hormone (ADH)
6.)parathyroid (PTH)

f. stimulates ovulation to occur within the ovaries of females and the production of progesterone that aids in maintaining pregnancy
g. secretion results in smooth muscle contractions within the uterine wall during childbirth
h. regulates sodium absorption and potassium excretion in the kidneys
Answer:
a= Antidiuretic hormone(ADH)
