Answer:
Vascular plants:
Can be large when fully grown.
May have seeds.
Can live farther from water.
Nonvascular plants:
Are small when fully grown.
Are always seedless.
Normally live in moist environments.
Explanation:
Plants can be classified regarding their flowering and their vasculature. When taking vasculature into consideration, they can be classified as Vascular Plants or Nonvascular plants.
Vascular plants have separate tubular tissues that are used to transport food and water, while nonvascular plants do not have these tissues. For this reason, nonvascular plants have a much harder time controlling the water inside them, and that's why they need to live in humid environments in order to survive. Vascular plants, on the other hand, can live in places farther from water.
Since they do not have vasculature, nonvascular plants are short in length, which makes it easier to survive considering the lack of tubular structures made for transport that vascular plants have.
Nonvascular plants do not have a vasculature, which means they do not have roots, stems, leaves nor seeds.

Within a population of butterflies, the color brown (B) is dominant over the color white (b) and 32% of all butterflies are white. Given this simple information, which is something that is very likely to be on an exam (teehee), calculate the following:
1. The percentage of butterflies in the population that are homozygous dominant
2. The number of heterozygous butterflies if the population contained 4,216 individuals
Answers
Answer:
48% Heterozygous of the population, 12% Homozygous dominant size.
Explanation:
Given the characteristics of its population,
Brown (B) predominates over white (b) color.
Recessive phenotype frequency (Q)= 40%= 0.4
According to the Hardy-Weinberg principle, the frequency is given by P and Q for a population with the dominant and recessive trait, where P+Q=1 preserves the equilibrium of the population allele.
So then, P = 1-Q
P=1-0.4=0.6
Heterozygotic butterflies = 2PQ
So, 2PQ= 2x0.6x0.4=0.48
That is, 48 percent of people are heterozygous
Homozygous dominant individual frequency = 1-(40 + 48) = 12 i.e. 12%
Answer:
C. 0.48

Reptiles are a class of vertebrates made up mostly of snakes, turtles, lizards, and crocodilians. The options (A), (B) and (E) are correct.
What are the characteristics of reptiles?Reptiles, as most commonly defined are the animals in the class Reptilia, a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates and rhynchocephalians.
Moreover, the major groups of living reptiles—the turtles (order Testudines), tuatara (order Rhynchocephalia [Sphenodontida]), lizards and snakes (order Squamata), and crocodiles (order Crocodylia, or Crocodilia)—account for over 8,700 species.
Therefore, the name "reptile" comes from Latin and means "one who creeps". All living reptile species are cold blooded, have scaly skin, and lay cleidoic eggs. They excrete uric acid (instead of urea), and have a cloaca. A cloaca is a shared opening for the anus, urinary tract and reproductive ducts.

As a scientist working for an anti-bioterrorism task force, you are asked to evaluate some biological samples for the presence of Yersinia pestis, the organism that causes the plague. After confirming that the samples do contain Y. pestis, you instruct your team to begin sequencing the strain. Since the genome sequence of Y. pestis is already known, why would sequencing this strain be useful?
Answers
Answer:
To gather relevant knowledge about their origin and to determine if the strain has been genetically modified.
Explanation:
A researcher researching with the anti-bioterrorism working group, they are required to assess certain blood specimens only for existence of Yersinia pestis, the organisms which causes the disease.
Since verifying that perhaps the varieties showed Y. Pestis, they are instructing their group to start sequence alignment the strains. So, this is to collect specific knowledge about their origin and to assess if the strain has also been genetically modified.

What is the advantage for birds of not having a bladder?
Answers
Answer:
Explanation:
The urinary bladder is a flexible sac that can expand and contract and that holds urine.
Urea is excreted mainly by birds and it happens to be the main chemical in urine, without the water in it, the birds excrete just solid droppings instead of as a liquid.
Now, birds physiology is such that they have only one opening to get rid of their (solid) waste and they do not have a bladder.

4. Is predation a density-dependent or density-independent factor?
Answers
Answer:
The correct answer is density-dependent factor.
Explanation:
The factors whose influences on the growth or size of the population changes with the density of the population are known as the density-dependent factors. The availability of food, disease, predation, and migration are some types of density-dependent limiting factors.
One of the density-dependent factors in nature is predation, predation confines various populations. The population of the prey and the predator encircle towards each other, with the population of the predator somewhat lagging behind the population of the prey.
With the increase in the population of the prey, the predator gets more to eat, and thus the population of the predator increases. With the increase in the predator population, pressure imparts on the prey population and it starts to decline. The decline in the availability of the food eventually makes the population of the predator to decline. Therefore, it can be seen that both the population of the prey and the predator are affected by predation, that is, a density-dependent factor.

what is the relationship between peripheral resistance and blood pressure ? between blood viscosity and blood pressure
Answers
Answer:
Peripheral vascular resistance (systemic vascular resistance, SVR) is the resistance in the circulatory system that is used to create blood pressure, the flow of blood and is also a component of cardiac function. When blood vessels constrict (vasoconstriction) this leads to an increase in SVR.
The relationship between BP and viscosity is such that, given a constant systolic BP, if blood viscosity increases, then the total peripheral resistance (TPR) will necessarily increase, thereby reducing blood flow. Conversely, when viscosity decreases, blood flow and perfusion will increase.
