If a man weighs 190 lb and eats 150 g protein per day, his protein intake is _____ of the recommended dietary allowance (rda)
The RDA for protein is 0.8 g per kilogram of body weight. This man's weight is 190 lb, or 86 kg; 86 kg × 0.8 = 69.1 g protein per day. Thus, an intake of 150 g is more than twice his RDA of 69.1 g of protein per day.
Recommended Dietary Allowance (RDA) of protein for adults is 0.8 g per kilogram of body weight. To determine your RDA for protein, multiply your weight in pounds by 0.36.The protein RDA for adults is 0.8 grams per kilogram of healthy body weight per day.
Proteins build muscle mass and contour, facilitate hair, nails and bone growth, regulate energy levels, and support chemical processes within the body which include enzyme, hormone and antibody production.

What is the approximate difference in sunita’s calorie need for basal metabolism from before to after the 10-pound weight loss?
a. 50 calories
b. 100 calories
c. 150 calories
d. 200 calories
Option (b.) 100 Calories will be the right one.
Basal metabolic rate (BMR) is the total number of calories your body needs to perform essential, life-sustaining functions which include circulation, breathing, cell production, nutrient processing, protein synthesis, and ion transport.
Generally a person burns calories continuously throughout the day in order to carry out basic life functions, for example-breathing, circulation, and digestion.
Equation to Calculate Your BMR:-
There is an equation given by Harris-Benedict which is often used to estimate basal metabolic rate which is mentioned below:-
Men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) - (5.677 x age in years)
Women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)

The _ states that the forces that are changing Earth's surface today are the same forces that changed Earth's surface in the past
The uniformitarianism states that the forces that are changing Earth's surface today are the same forces that changed Earth's surface in the past which is because of the presence of the same types of agents being present.
What is Uniformitarianism?This type of doctrine which was founded by James Hutton and made popular by Charles Lyell in the 19th century talks about how the earth's geologic processes are the same as a result of the agents of weathering being the same in this type of scenario.
Weathering on the other hand can be defined as the process in which rocks are broken down into smaller particles to form different types of soil. The agents of weathering has been the same today and in the past which makes it constant.
Hence, the reason why Uniformitarianism was chosen as the most appropriate choice.

The arrival of a nerve impulse at the synaptic knob of a motor neuron causes synaptic vesicles to release _____ into the synaptic cleft.
A Final statement or concluding statement
The arrival of a nerve impulse at the synaptic knob of a motor neuron causes synaptic vesicles to release acetylcholine into the synaptic cleft.
What is released by synaptic knob?A neurotransmitter-containing membrane-enclosed vesicle fills the synaptic knob. The synaptic knob's arrival of an action potential opens [tex]Ca^{2+}[/tex] channels in the plasma membrane. Some of the vesicles undergo exocytosis in response to the [tex]Ca^{2+}[/tex] influx. The synaptic cleft receives the discharge of their neurotransmitter. The receptors on the postsynaptic membrane are where the neurotransmitter molecules bind.

Bacteria are prokaryotes, fungi and protists are eukaryotic organisms and viruses are not living.
In what ways it is possible to distinguish prokaryotes from eukaryotes?Bacteria (e.g., E coli) are prokaryotic organisms whose cells don't have nuclei or membrane bound organelles, reproduce by asexual ways such as binary fission, and they are beneficial as descomposers.
Some common diseases caused by bacteria include tetanus (Clostridium tetani), pneumonia (Klebsiella pneumoniae), cholera (Vibrio cholerae), etc.
Moreover, protists (e.g. algae) and Fungi (e.g. Saccharomyces cerevisiae) are eukaryotic organisms that have cell nuclei and organelles, can reproduce by asexual reproduction, can perform photosynthesis (algae) or acts as decomposers (fungi).
Some common diseases caused by protists/protozoans include malaria (Plasmodium), sleeping sickness (Trypanosoma), etc.
Some common diseases caused by fungi include aspergillosis (Aspergillus), candidiasis (Candida albicans), etc.
Finally, viruses are not living because they need a host to survive and are also useful as vectors to design gene therapy techniques.
Some common diseases caused by viruses include AIDS (HIV retrovirus), dengue fever (Flaviviridae viruses), etc.
Bacteria are used to produce insulin and other natural medications, viruses are used as carriers for the treatment of diseases, protozoans can enhance the fertility of soils and fungi are employed in the preparation of foods.

K-strategists might include which species?

B. mice
C. humans
D. shrimp
Potential K- strategists include humans.
K- strategist:
The term "K-selected" or "K-strategist" refers to species whose populations vary at or close to the carrying capacity (K) of the ecosystem in which they live. Compared to r-selected species, K-strategist species have remarkably constant populations and generate relatively few offspring, but those offspring typically grow to be rather big. Lengthy gestation durations of many weeks, slow development (and hence prolonged maternal attention), and long longer lifespans are traits of K-selected species. Additionally, they typically live in ecological groups that are generally stable, including premature or climax forests.
R-strategist:
They are creatures that have high reproduction rates followed by high death rates, resulting in populations with wildly variable numbers, according to the concept of r-selected species (or r-strategist). This term is based on the concept of "r," a variable in the ecology of animal populations that denotes a species' maximal reproductive potential. The populations of r-selected species will be small outside of the mating season. R-selected organisms begin to generate a lot of progeny as soon as reproduction begins.
Therefore it is concluded that the final choice is option C, i.e., humans.

A scientist samples a population of butterflies and finds that 56% are heterozygous at a particular locus. If the population is in hardy-weinberg equilibrium, what should be the frequency of the homozygous individuals in this population?.
0.44 the frequency of the homozygous individuals in this population.
What is Hardy-Weinberg principle ?
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
From the Hardy Weinberg Law of Population and Genetics,
We have
x²+2xy+y²=1 and
x+y=1
where
x = frequency of the dominant allele in the population
y = frequency of the recessive allele in the population
x2 = percentage of homozygous dominant individuals
y2 = percentage of homozygous recessive individuals
2xy = percentage of heterozygous individuals
Given 2xy = 0.56
from here, y=0.28/x, (the frequency of the recessive allele ) can be obtained
we need to find 'x'
recall, x+y=1, x=1-y
substituting this gives us
y=0.28/(1-y), which becomes,
y(1-y)=0.28
y²- y + 0.28 (quadratic equation)
Solving this to find 'y' gives two imaginary values of y = 0.44 but ,
There is no imaginary solution .

If an organism is catalase positive, which aerotolerance categories could it be in?
If an organism is catalase positive, it is in staphylococcus aerotolerance categories.
Catalase testing is used to distinguish between Streptococci (catalase-negative) and staphylococci (catalase-positive). The catalase enzyme works to counteract hydrogen peroxide's bactericidal effects. Hydrogen peroxide (H2O2) is quickly broken down into water and oxygen by catalase.
Bacteria that use oxygen for breathing create the enzyme catalase, which shields them from the harmful byproducts of oxygen metabolism. Strict aerobes and facultative anaerobes are both catalase-positive bacteria, although they can all respire utilising oxygen as a terminal electron acceptor. Anaerobes or facultative anaerobes that solely ferment and do not respire using oxygen as a terminal electron acceptor can be catalase-negative bacteria (i.e. Clostridium).
