Answer:
Most insects change in form during their development, and the successive stages are not all alike. This change in form is called metamorphosis. It is controlled by a juvenile hormone secreted by glands in the insect's head. The juvenile hormone is released during each molt, but the amount decreases each time.
Explanation:
A flying object is moving at 150 m/s. It makes a complete and final stop in 12 seconds. Calculate the object’s acceleration.
plzzzzzzzzzzz
Answer:
12.5m/s^2
Explanation:
Acceleration of an object can be calculated by using the formula;
a = v-u/t
Where; a= acceleration
v= final speed
u= initial speed
t= time
According to this question, the flying object is moving at 150m/s, meaning that ∆V = (v-u) is 150m/s, where initial speed is 0m/s.
Since time is 12s, the acceleration is thus:
a = 150-0/12
a= 150/12
a= 12.5
Hence, the acceleration of the flying object is 12.5m/s^2
What colors of light are most useful to plants during photosynthesis
While most plants reflect more green than any other in the visible spectrum, a relatively small percentage of green light is transmitted through or reflected by the leaves.The majority of green light is useful in photosynthesis.
Although green is the visible spectrum color that most plants reflect the most light from, only a small portion of green light.
It actually passes through or is reflected by the leaves. Most green light is beneficial for photosynthesis.
Thus, Plants, algae, and some microorganisms use the process of photosynthesis to convert sunlight into energy. Water and carbon dioxide (CO2) are chemically changed into food (sugars) and oxygen during the process.
The pigment chlorophyll, which gives plants their green colour, is frequently used in the chemical reaction. Our planet's atmosphere is abundant in oxygen because of photosynthesis.
Thus, Although green is the visible spectrum color that most plants reflect the most light from, only a small portion of green light.

In rats, gene B produces black coat color if the genotype is B-, but black pigment is not produced if the genotype is bb. At an independent locus, gene D produces yellow pigment if the genotype is D-, but no pigment is produced when the genotype is dd. Production of both pigments results in brown coat color. If neither pigment is produced, coat color is cream. A third independently assorting gene involved in determination of coat color in rats is the C gene. At this locus, the genotype C- permits expression of pigment from genes B and D. The cc genotype, however, prevents expression of coat color and results in albino rats. For each of the following crosses, determine the expected phenotypes and their ratio in progeny:Part ABbDDCc x BbDdCcExpress your answer as five numbers separated by colons.

A genetic trait is inherited via the Y chromosome such that for a father with the trait, his male offspring have a 25% chance of inheriting it but his female offspring cannot inherit it. Suppose that in a certain population, 40% of offspring are male and offspring genders are independent events. For a father with the trait who has two offspring, what is the probability that the older offspring has the trait and the younger offspring does not?
Answer:
0.09
Explanation:
let us define these events as
O = older
Y = younger
Prob(O) = 40% offspring x 25% chance of inheritance
= 0.4x0.25
= 0.1
P(Y') = 40% offspring x (1-25%) +(1-40%)x1
= 0.4x0.75 + 0.6x1
= 0.3+0.6
= 0.9 this is the probability of having the trait.
Probability that older offspring has trait but younger does not have it
Prob(O n Y') = prob(O) x Prob(Y')
= 0.1x0.9
= 0.09
Nhich type of molecule that can be found in living things lacks carbon atoms?
O protein
O carbohydrate
O fat
water
i think protein is the answer of this question.
The type of molecule which can be found in living things that lacks carbon atoms are water molecules. Thus, the correct option is D.
What are Water molecules?Water has the simple molecule which has mainly composed of two small, positively charged hydrogen atoms and one large negatively charged oxygen atom. When the hydrogen atoms bind to the oxygen atom, it creates an asymmetrical molecule with a positive charge on one side and a negative charge on the other side of the compound.
The biomolecules are the substances which are found inside the body of a living organism. Water molecules are the type of molecules which can be found in the living things which lacks carbon atoms.
Therefore, The type of molecule which can be found in living things that lacks carbon atoms are water molecules. Thus, the correct option is D.

You need to determine the sequence of a linear decapeptide. The following experiments have been performed:
1. Edman degradation generates 10 amino acids: Q, E, M, R, K, C, F, P, Y, A.
2. Cyanogen bromide (CNBr) cleavage gives two pentapeptides (5 aa’s).
3. Trypsin cleavage gives two tripeptides (AMR and QFK), and a tetrapeptide.
4. Chymotrypsin cleavage gives a dipeptide QF, a single amino acid, and a heptapeptide (7).
5. The C-terminal residue is identified as Cys using carboxypeptidase C, which removes amino acids from the C-terminal end of a polypeptide.
Give two possible sequences for the decapeptide, using aa three-letter codes.
Answer:
The two possible sequences for the decapeptide using a three-letter codes
are :
ii) Q F K A M R P E Y C
II) Q F K A M R E P Y C
Explanation:
The two possible sequences for the decapeptide using a three-letter codes
are :
ii) Q F K A M R P E Y C
II) Q F K A M R E P Y C
This possible sequences are gotten from Edman degradation , Cyanogen bromide and Trypsin digestion and also Chymotrypsin digestion. also note that the codons used to code these amino acids can also be written in a sequence to obtain a three code sequence

Know all STIS: pathophysiology, etiology, clinical manifestations, diagnostic tests, treatment, and complications. How is each transmitted during pregnancy to the fetus?
Know the different stages of syphilis; what organism causes each STI and is it viral, bacterial etc.?
Do you treat both partners and why?
What age group has the greatest risk of STIs and why?
What causes cervical cancer?
Answer and Explanation:
1. Each of the elements shown are transmitted to the fetus during pregnancy through the mother's bloodstream and through the umbilical cord, where the fetus receives all the support for its body, such as oxygen, nutrients, hormones, treatments, tests, among others. others. Some of them are possible through the visualization of the fetus and the manipulation of the products written by him.
2. Syphilis is a sexually transmitted infection caused by the bacteria Treponema pallidum. This infection has three phases (primary, secondary and tertiary) that are interspersed with asymptomatic periods, which aggravates the severity of the disease, since it presents itself as a silent evil. The primary phase occurs between 3-4 days after infection and its main symptom is the presence of wounds throughout the body, especially in the genitals. If not treated properly, 8 weeks later the secondary phase appears, where the infected person has red spots on the body, itching, fever, muscle pain and swollen and painful lymph nodes in the neck and armpit. When left untreated, the disease progresses to the tertiary stage where it presents severe symptoms that are difficult to diagnose. The disease affects the brain, eyes, heart, joints and the nervous system, causing severe headaches and even epilepsy.
3. It is necessary for both partners to be treated in case of any sexually transmitted infections. This must be done, primarily because the transmission occurred between these partners, which indicates that both have the disease and can reinfect themselves, or infect other people.
4. People aged 15 to 24 are at the greatest risk of being infected with a sexually transmitted infection. This is because people at this age are more likely to not get a steady partner and to adopt behaviors that facilitate infection such as having sexual contact without adequate protection.
5. What causes cervical cancer is the untreated infection of a virus called HPV. This type of cancer is usually asymptomatic, but in the early stages it may show bleeding from the genitals after sexual intercourse.
