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
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

Consider two different traits in mice affecting tail length and fur color. A two-factor cross was made involving true-breeding mice with short tails and white fur to wild-type mice with long tails and brown fur. All F1 offspring had long tails and brown fur. The F1 offspring were then crossed to mice with short tails and white fur. The following phenotypic results were obtained:
118 long tails, brown fur 77 long tails, white fur 114 short tails, white fur 81 short tails, brown fur
Required:
Construct a null hypothesis about these two genes and the expected ratios of the offspring from the cross.
Answer:
See the answer below
Explanation:
Null hypothesis: The two genes are independently assorting and therefore, are not linked to each other.
Let A represents the allele for tail length and B for fur color. Long-tail A is dominant over short tail a while brown fur B is dominant over white fur b.
For the first cross involving true-breeding mice:
AABB x aabb
F1 AaBb (long tails and brown fur)
For the second cross:
AaBb x aabb
4 AaBb - Long-tail, brown fur
4 Aabb - Long tail, white fur
4 aaBb - short tail, brown fur
4 aabb - short tail, white fur
Since the phenotypic ratio from the cross is 1:1:1:1, if the null hypothesis was to be true, it means that the expected phenotype ratio should be 1:1:1:1.
In order to test this hypothesis, we use Chi-square:
phenotype O E X^2
Long-tail, brown fur 118 97.5 [tex]\frac{(118-97.5)^2}{97.5}[/tex] = 4.31
Long tail, white fur 77 97.5 4.31
short tail, brown fur 81 97.5 2.79
short tail, white fur 114 97.5 2.79
Total 14.2
Degree of freedom = 4 - 1 = 3
Critical Chi-square value = 7.815
The calculated Chi-square value is more than the critical value, hence, the null hypothesis is rejected.

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.

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.

Which statement best describes a benefit of conducting a comparative investigation over collecting data from the Internet?
1 A comparative investigation can be repeated in a short time while collecting the continuous data from the Internet takes longer.
2Conducting a comparative investigation is always less expensive than an investigation in which data is obtained from the Internet.
3 Conducting a comparative investigation is always less time consuming than obtaining data from the Internet.
4 A comparative investigation can provide a wider range of data than can be obtained from the Internet.
Answer:
The correct option is 4
Explanation:
Comparative investigation involves the collection of data from different "subjects" (including organisms, object or characteristics) or obtaining data under different conditions (such as seasons, years or locations) for the purpose of comparison. This type of investigation is both time and capital intensive; meaning it requires a lot of time and money. It however provides a larger and wider range of data that might not be available through other "independent investigations" because a large amount of subjects is usually studied for proper and accurate comparisons.
Answer:
D- A comparative investigation can provide a wider range of data than can be obtained from the Internet.
