Answer:
The correct answer is - OoBb
Explanation:
As it is given that:
O- B- snakes = brown
O- bb = orange
oo B = black
oo bb = albino
And here, the cross between an orange snake and black snake which means:
P0 : ooBB × OObb
offspring of f1 would be =
F1 : OoBb
self cross of f1 offsprings
F2 : OoBb × OoBb
Gametes OB Ob oB ob
OB OOBB OOBb OoBB OoBb
Ob OOBb OObb OoBb Oobb
oB OoBB OoBb ooBB ooBb
ob OoBb Oobb ooBb oobb
here we get approximately similar as Phenotypic ratio as mention in question- 9 : 3 : 3 : 1 or 100:25:22:13
Thus, the correct answer would be: OoBb

Read the paragraph from the section "Types Of
Isolation."There are biological properties of organisms
that prevent breeding across different species. They are
known as reproductive isolating mechanisms (RIMs). A
mechanism is a process or method. Which option is the
BEST definition of "properties" as it is used in the
paragraph above?
The correct answer is B. Traits or features that take effect.
Explanation
Property is a word to designate any quality that identifies identifying something or someone, distinguishing it from its peers. It can refer to different issues such as its characteristics, capabilities, possibilities, physical appearance, among others. According to the text, "There are biological properties of organisms that prevent breeding across different species". So the answer is B. Traits or features that take effect.
If a DNA strand contains 12% thymine, it also contains ____
a. 12% A, 38% G, 38% C
b. 12% A, 12% G, 38% C
c. 12% A, 12% G, 12% C
d. 38% A, 12% G, 38% C
Answer:
If G = 14, then C = 14 and G + C is 28. Thus A + T. The percent of adenine in a double-stranded DNA is 38. Therefore G + C = 100 - 76 = 24, and C = 24/2 = 12 percent.

examples. Original DNA: ATCCGCTTACG
a. UUGGCGAAUCG: __________________
b. UATGGCGAAUCG: _________________
c. UGGCGAAUCG:__________________
Answer:
a. the second nucleotide is wrong. It is a U but should be an A. No other nucleotides were effected by this, only the one was effected. This is a Point (Substitution) Mutation.
b. the third nucleotide is wrong. It is a T that was inserted. As you can see, the rest of the nucleotides are right, but since the T was added, it will mess up how the rest of the sequence is read. It will be read UAT GGC GAA... instead of UAG GCG AAU... see how it messed it up? This is an Insertion (Addition) Mutation.
c. the second nucleotide was deleted. This is called a Deletion Mutation. It will mess up the rest of the sequence, similar to how the example above did.

1. What is a biogeochemical cycle?
2. What drives, or powers, the water cycle?
3. What causes water to condense and form clouds?
Answer:
1. In ecology and Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic and abiotic compartments of Earth.
2. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Rising vapor cools and condenses into clouds.
3. Heated by sunshine, the ground heats the air just above it. That warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense. ... The air cools as it rises, and eventually clouds form.

Radioimmunoassay (RIA) of peripheral blood indicated elevated TSH levels. A TSH stimulation test did not increase the output of thyroid hormones from the thyroid gland.
a. What endocrine organ is involved here?
b. Is this a primary or secondary disorder? Why? (Is a TSH or TRH determination necessary for your diagnosis?)
c. Describe the feedback loop involved, indicating if there is an increased or decreased TSH level.
d. List several defects that could cause these symptoms.
e. Would you expect to find a palpable goiter? Explain your answer.
f. Describe a suitable treatment for this individual.
Answer:
1. Thyroid gland is the endocrine gland that is involved here.
2. TSH stimulation test did not show an increase in the output of thyroid hormones secreted from thyroid glands which makes it a primary disorder. The determination of TSH or TRH gives an idea about hypothyroidism if it is due to feedback inhibition of the pituitary or absence of TSH hormone from the pituitary, however, Circulating levels of TRH not necessary.
3. The feedback loop involves the following:
TRH hormone secreted from the hypothalamus triggers the anterior pituitary to secret TSH that in turn triggers the relapsing of the T3 and T4 levels by the thyroid glands. If there is a low level of T3 and T4 hormones then negative feedback takes place and increases the TSH output.
4. symptoms:
Not able to uptake the iodide into the cells of the thyroid gland
Defects in the conversion of iodide to iodine
tyrosine molecule iodization
secretion of the hormones from the Tg molecules
Less TSH receptors on the gland.
5. The chronic TSH stimulation due to negative feedback may cause hypertrophy of the gland, results in goiter formation.

8. a) How are the events in the menstrual cycle triggered by the body? (1 point)

There is a supply of undeveloped eggs in the ovaries. At the beginning of the menstrual cycle, between 6 and 12 undeveloped eggs in the ovaries start to mature. A layer of cells grows around them. At around day 5 of the menstrual cycle, the biggest follicle will continue to grow for another week. At around day 14, the follicle breaks apart, and the wall of the ovary ruptures. The egg is released from the ovary into the fallopian tube, where it can get fertilized. This process is called ovulation. The uterus also changes during the course of the menstrual cycle. It has a lining of cells on the inside, kind of like a cushion with a lot of blood vessels. Fallopian tubes connect the ovaries and the uterus. The uterine cycle begins with menstruation. This is the process through which most of the lining and blood from the last uterine cycle are cleared out of the uterus to prepare for a new attempt at pregnancy. Starting at around day 5, the lining starts to grow. It builds back up to prepare a place for the egg to grow if it gets fertilized. After ovulation, the egg reaches the oviduct. If sperm cells have entered the vagina during intercourse, fertilization may occur at any time in the next two weeks. Then the fertilized egg will move into the uterus and implant itself into the lining, where development will begin.
Please mark BRAINLIEST!
The events in the menstrual cycle are primarily triggered by hormonal signals from the body. The menstrual cycle is a complex process regulated by the interplay of hormones produced by the hypothalamus, pituitary gland, and ovaries.
1. Hypothalamus: The hypothalamus, a region of the brain, releases gonadotropin-releasing hormone (GnRH) in a pulsatile manner. GnRH stimulates the pituitary gland.
2. Pituitary gland: In response to GnRH, the pituitary gland secretes two important hormones: follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
3. Follicular phase: At the beginning of the menstrual cycle, FSH stimulates the growth and maturation of ovarian follicles, which contain the developing eggs (oocytes).
As the follicles grow, they produce estrogen, a hormone that helps prepare the uterus for a possible pregnancy.
4. Ovulation: As the estrogen levels rise, it triggers a surge in LH production by the pituitary gland. The LH surge leads to the release of a mature egg from the ovary, a process called ovulation.
5. Luteal phase: After ovulation, the ruptured follicle in the ovary transforms into a structure called the corpus luteum. The corpus luteum produces progesterone, which prepares the uterus for potential implantation of a fertilized egg.
6. Menstruation: If pregnancy does not occur, the levels of estrogen and progesterone decline. This drop in hormone levels triggers the shedding of the uterine lining, resulting in menstrual bleeding.

Newton's 2nd Law is F= ma. Write a problem that gives the mass and the acceleration of an object and asks us to find the force.
Answer:
An object having a mass of 20kg is pushed by John and it then accelerates down the inclined plane at a rate of 0.5m/s². Find the force applied on the object.
Explanation:
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
For example, an object having a mass of 20kg is pushed by John and it then accelerates down the inclined plane at a rate of 0.5m/s². Find the force applied on the object.
Given the following data;
Mass = 20kg
Acceleration = 0.5m/s²
To find the force;
Force = mass * acceleration
Substituting into the equation, we have;
Force = 20 * 0.5
Force = 10 Newton.
