Answer:
Function: To improve the animals´ movement and displacement on water.Not all frogs have well-developed membranes. Those with terrestrial habits exhibit reduced interdigital tissue.Explanation:
The interdigital membrane is the skin between the fingers and toes of the animals. This tissue is resistant and flexible. Its expansion varies among species and depends on their habits. The principal function of these membranes is to improve the animals´ movement and displacement on water. This tissue represents a broader area that provides resistance to water so the animal can swim faster and longer. On the ground, these membranes also can be useful while jumping, but this is not its principal function. The development of the interdigital membrane show variation among amphibians. In those taxa that spend most of their time in the water, the membranes are extensive and well-developed. On the contrary, groups that spend most of their lives on the ground, on trees, and other vegetation, exhibit poorly-developed membranes or almost absent.Which nitrogen bases (codon) in the mRNA code for the amino acid Valine?

a. The logistic equation reflects the effect of density-dependent factors, which can ultimately stabilize populations around the carrying capacity. b. Density-independent factors have an increasingly greater effect as a population's density increases. c. High densities in a population may cause physiological changes that inhibit reproduction. d. Because of the overlapping nature of population-regulating factors, it is often difficult to precisely determine their cause-and-effect relationships. e. The occurrence of population cycles in some populations may be the result of crowding or lag times in the response to density-dependent factors.
Question:
Which of the following is an incorrect statement about the regulation of populations?
Answer:
b. Density-independent factors have an increasingly greater effect as a population's density increases.
Explanation:
A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.
Generally, these populations may be divided into a fraction of the population (subpopulation) based on certain factors and reasons.
Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.
Mathematically, the population change equation is given by the formula;
Population Change = (Natality - Mortality) + (Immigration - Emigration)
Population regulation can be defined as a biological process that balances limiting factors affecting the growth of a population based on density. The factors that regulate the growth of a population are divided into two (2) main categories and these includes;
I. Density-independent factors.
II. Density-dependent factors.
Density-dependent are regulating factors such as predation, diseases, and competition that affect the size of the population of living organisms through decreasing or increasing mortality and birth rate.
Furthermore, density-independent factors do not have an increasingly greater effect as a population's density increases. Thus, its effect are reduced as a population's density increases in size.
Which of the following is not an example of an ecosystem service?
a. water is purified as it trickles down through a wetland
b. green plants provide a carbon sink that can help reduce global warming
c. creativity born from interactions with nature
d. all of these are examples of ecosystem services
I could really use some help
The one that is not an example of an ecosystem service is creativity born from interactions with nature. The correct option is c.
What is an ecosystem?An ecosystem is a geographical area in which plants, animals, and other species, as well as weather and scenery, coexist to produce a life bubble. Ecosystems comprise both biotic (living) and abiotic (nonliving) components.
Plants, animals, and other species are examples of biotic factors. A marine ecosystem, for example, contains 32% of the world's producers because water covers three-thirds of the earth's surface and provides a natural habitat for a diverse range of small and large living species and plants.
Therefore, the correct option is c. creativity born from interactions with nature.

The orbits of the planets are elliptical
Includes eight planets.
The solar system
Explanation:
The main difference between the heliocentrical and geocentrical model is that in the first one, the Sun is in the center and the planets are around it, while in the second model, the Earth is in the center and the Sun, the moon, and the planets are around it.
Also, the geocentrical model stated that there were five planets, Mercury, Venus, Mars, Jupiter, and Saturn. These planets had circular orbits. In other words, they have a circular motion around the Earth, and this one was still in the center of the system.
In the heliocentric model, there are eight planets, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, and they all rotate in elliptical orbits around the Sun. The Heliocentric model is also called the solar system since its central star is the Sun, and the planets are around it.

In griffins, the allele for black feathers (B) is dominant over silver feathers (b) which are recessive. Two black griffins are crossed and have a silver offspring. What is the genotype of the parents?
Answer:
The correct answer is - Bb and Bb.
Explanation:
In this case, there are two traits decided by the black "B" allele that is dominant over "b" which is silver. In this case the cross between two black feather birds and the there would be genotype:
BB and BB or Bb and Bb or Bb and BB
1. In first case, and the third case, there is no or only one allele for the silver trait so the correct answer would be - Bb and Bb
B b
B Bb Bb
b Bb bb
thus, the correct answer is - bb which is silver feather.

EOC Biology STAAR Test Prep
In humans blood type is determined by the A, B, and O alleles. The A and B alleles are codiminant to each other and dominant over the O allele. An individual with the AO genotype and an individual with the BO genotype can produce offspring with which of the following phenotypes.
O only
A or B only
A, B or O only
A, B, AB, or O
Please explain, also this is not a test its a test PREP
Answer:
D. A, B, AB, or O
Explanation:
We can start by visualizing all the possible genotypes of the offspring by drawing a Punnett square, which is a visual representation of the different possible combinations of alleles:
Individual 1 = AO, Individual 2 = BO
A O
B AB BO
O AO OO
Here we can see that there are 4 possible genotypes: AB, BO, AO and OO based on the alleles of the parents. Now we can match the genotypes to phenotypes to answer the question:
A and B are codominant, meaning that both will be expressed equally if both are present. Therefore the genotype AB will result in an AB phenotype.
Next, since A and B are both dominant over O, they are the alleles that will be expressed in the phenotype if paired with an O. This means that the genotype AO will result in an A phenotype, and likewise, genotype BO will result in phenotype B.
Finally in the genotype OO, although O is a recessive allele, there are no dominant alleles here to mask them, therefore O is expressed in the phenotype.
Hence, from the genotypes AO and BO, the possible offspring genotypes are AB, BO, AO and OO, translating to the possible phenotypes: A, B, AB or O.

Convection in the troposphere causes
•wind •ocean currents •both wind and ocean currents •neither wind nor ocean
Explanation : The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles ) causes convection currents, large-scale patterns of winds that move heat and moisture around the globe. As air rises, expands, and cools, water vapor condenses and clouds develop.
are these correct? or no?
Answer:
yes/no
Explanation:
1. looks correct!
2. i think that is the third choice because I learned that during interphase, the cell grows and makes a copy of its DNA. I learned this a while ago so I'm not 100% sure its correct. :)
You look at the cell under a microscope and see that it has 34 body chromosomes and one nucleus. Second view: Several hours later, you look at the same cell again and see that it has double the amount of DNA and one nucleus. Third view: A little while later, you see that it has one cell with 68 chromosomes and two nuclei. What stage of the cell cycle was this cell in when you viewed it at each time point
Ecological interactions can be categorized as competition, exploitation, or positive. Describe the types of interactions that fall into these categories, and provide an example of each type of interaction.
Answer:
Competition is an interaction between organisms or species in which both the organisms or species are harmed. Limited supply of at least one resource used by both can be a factor. This example is if two lions get into a fight and they end up hurting each other.
Exploitation competition occurs when individuals interact indirectly as they compete for common resources, like territory, prey or food. An example of this is when people are farming and they are trying to get the best food available but someone else might have already gotten it.
Commensalism is a positive type of ecological interaction between two species in an ecosystem. In commensalism, the association occurs between members of two different species where one species is benefited the other is neither benefited nor harmed. An example of this is tree frogs who use trees as protection.
Explanation:
2. Energy flows through Earth's spheres and changes along the way. Describe how energy is conserved in these systems. (2 points)
Answer:
Teaching about energy and physical processes is supported by 7 key concepts:
2.1 Earth is constantly changing as energy flows through the system. Geologic, fossil, and ice records provide evidence of significant changes throughout Earth's history. These changes are always associated with changes in the flow of energy through the Earth system. Both living and non- living processes have contributed to this change.
2.2 Sunlight, gravitational potential, decay of radioactive isotopes, and rotation of the Earth are the major sources of energy driving physical processes on Earth. Sunlight is a source external to Earth, while radioactive isotopes and gravitational potential, with the exception of tidal energy, are internal. Radioactive isotopes and gravity work together to produce geothermal energy beneath Earth's surface. Earth's rotation influences global flow of air and water.
2.3 Earth's weather and climate are mostly driven by energy from the Sun. For example, unequal warming of Earth's surface and atmosphere by the Sun drives convection within the atmosphere, producing winds, and influencing ocean currents.
2.4 Water plays a major role in the storage and transfer of energy in the Earth system. The major role water plays is a result of water's prevalence, high heat capacity, and the fact that phase changes of water occur regularly on Earth. The Sun provides the energy that drives the water cycle on Earth.
2.5 Movement of matter between reservoirs is driven by Earth's internal and external sources of energy. These movements are often accompanied by a change in the physical and chemical properties of the matter. Carbon, for example, occurs in carbonate rocks such as limestone, in the atmosphere as carbon dioxide gas, in water as dissolved carbon dioxide, and in all organisms as complex molecules that control the chemistry of life. Energy drives the flow of carbon between these different reservoirs.
2.6 Greenhouse gases affect energy flow through the Earth system. Greenhouse gases in the atmosphere, such as carbon dioxide and water vapor, are transparent to much of the incoming sunlight but not to the infrared light from the warmed surface of Earth. These gases play a major role in determining average global surface temperatures. When Earth emits the same amount of energy as it absorbs, its average temperature remains stable.
2.7 The effects of changes in Earth's energy system are often not immediately apparent. Responses to changes in Earth's energy system, input versus output, are often only noticeable over the course of months, years, or even decades.

In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. What percentage of offspring are expected to be chestnut?
Answer:
This question is incomplete, the complete question is as follows:
- In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. A homzygous black horse crosses with a chestnut horse.
What percentage of offspring are expected to be chestnut?
The answer is 0%
Explanation:
This question involves a gene coding for color in horses. The allele for black coloring (B) is dominant over the allele for chestnut coloring (b) is recessive.
According to this question, if a homzygous black horse (BB) crosses with a chestnut horse (bb), the following gamete will be produced by each parent;
BB - B only
bb - b only
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
Bb, Bb, Bb, Bb
All of these offsprings are phenotypically black colored although heterozygous in genotype. Hence, 0% of offspring are expected to be chestnut.
