Answer:
It should be geosphere.
Explanation:
Humans and baboon have noses with nostrils that face downward, but many other primates have noses with nostrils that face out to the sides. Humans and baboons are also more closely related to each other than they are to primates with outward-facing nostrils. Therefore, the fact that both humans and baboons share the downward-facing nostril orientation is an example of
Answer:
a shared derived trait.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, weight, handedness, freckles, curly hair, hair color, blindness, complexion, height, etc.
All humans and baboons are created having noses with nostrils underneath i.e facing downwards but other primates such as platyrrhines have their nostrils facing sideways (face out to the side). Also, humans and baboons shared close similarities with each other when compared than they share with the primates having a outward-facing nostrils.
This ultimately implies that, both humans and baboons sharing the downward-facing nostril orientation is an example of a shared derived trait.
A shared derived trait can be defined as a trait or characteristic that is shared between two lineages and subsequently evolves leading up to a clade, which is a distinguishing feature from other species.

g Neuron A and neuron B interact with neuron C. Neuron A will produce an IPSP of -2mV in neuron C; neuron B produce an EPSP of 3mV in neuron C. The resting membrane potential is -70mV and the threshold is -50mV. Neuron A fires 6 times rapidly at the same time that neuron B fires 4 times rapidly. What is the resulting membrane potential in neuron C
Answer:
-70 mV
Explanation:
Given that Neuron A and Neuron B interact with Neuron C
Neuron A produces ; - 2mV of IPSP and fires 6 times
Neuron B produces ; 3mV of EPSP and fires 4 times
Resting potential = - 70mV
threshold = - 50mV
The resulting membrane potential in neuron C
= -70 + 6(-2) + 4(3)
= -70 - 12 + 12 = -70 mV

The difference in the chromosome arrangement during meiosis in the metaphase plate can lead to greater genetic diversity in a population. Explain your answer
Explanation:
Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell. Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes!
Apart from this reduction in chromosome number, meiosis differs from mitosis in yet another way. Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.
Finally, unlike mitosis, meiosis involves two rounds of nuclear division, not just one. Despite this fact, many of the other events of meiosis are similar to those that occur in mitosis. For example, prior to undergoing meiosis, a cell goes through an interphase period in which it grows, replicates its chromosomes, and checks all of its systems to ensure that it is ready to divide. Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase. A key difference, however, is that during meiosis, each of these phases occurs twice — once during the first round of division, called meiosis I, and again during the second round of division, called meiosis II.

Answer:
100% of the offspring would be black fur, black eyes (16/16)
Explanation:
(Because the info. wasn't included here, I'm assuming black fur and black eyes are dominant, BBEE, to the recessive white fur and red eyes, bbee)
For BBEE x bbee, you'd create a typical dihybrid true-breeding punnett square , where the first top row would be BE , BE, BE , BE , and the vertical/side row would be be, be, be, be.
Cross these alleles as you would typically for any punnett square, and you'd see that all the offpsring would result in BbEe genotypes, which is true of any true-breeding dominant x recessive cross, which always results in the dominant phenotype being 100%.
So...
Black Fur and Black Eyes : 16/16 (100%)
Black Fur and Red Eyes: 0/16
White Fur and Black Eyes: 0/16
White Fur and Red Eyes: 0/16

How is mitosis different in plants and animals?
Answer:
The main difference is cell plate formation and how they form the daughter cells during cytokinesis. In plants, they lack centrosomes. A new cell plate will form between the daughter cells for the future cell wall. In animal cells the cell membrane will rather constrict to separates the parent cell into the daughter cells. Plants also do not undergo cell furrowing, unlike animals cells.
A recessive allele for blue eyes (b) has a frequency of .3 in population 1 and a frequency of .15 in population 2. Pollution causes a number of people in population 1 to go to population 2. After they migrate 35% of the people in population 2 consist of people from population 1. What would be the frequency of blue eyes in population 2 after the migration
Answer:
The frequency of blue eyes in population 2 after the migration is q₂´ = 0.195 ≅ 0.2
Explanation:
Whenever migration, m, occurs between two populations, there is genetic flow going on. Genetic flow is an evolutive strength only if migration > 0 and if the allelic frequency in one generation is different from the allelic frequency in the next generation.
Genetic flow acts homogenizing the allelic frequencies between the two populations, and it might introduce variability into the new one.
For genetic flow to be possible, there needs not only the movement of the genes from one population to the other but also the reproduction process on the new population. Hence, it involves an interaction between the dispersion pattern and the reproductive system.
Available data:
Population 1 → frequency of the recessive allele b = 0.3Population 2 → frequency of the recessive allele b = 0.15m = proportion of gametes coming from the population 1 = 30% = 0.31-m = proportion of gametes that remain in the populationp = frequency of the dominant allele in population 1 before migrationq = frequency of the recessive allele in population 1 before migrationp´ = frequency of the dominant allele in population 2 after migrationq´ = frequency of the recessive allele in population 2 after migrationTo calculate the frequencies of the gametes (p1, q1, p2, q2) after migration, we can use the following equations:
p₁’ = p₁ (1 - m) + p₂ x mq₁´ = q₁ (1 - m) + q₂ x mp₂’ = p₂ (1-m) + p₁ x m q₂´ = q₂ (1 - m) + q₁ x mSo to know the frequency of blue eyes in population 2 after the migration, we just need to replace the terms in the equation for the given values, and then calculate q₂´.
q₂´ = q₂ (1 - m) + q₁ x m
q₂´ = 0.15 (1 - 0.03) + 0.3 x 0.3
q₂´ = 0.105 + 0.09
q₂´ = 0.195 ≅ 0.2

Of the babies that survive, however, few will have birth defects related to the exposure, regardless of how much radiation they were exposed to. Large radiation doses to the fetus during the more sensitive stages of development (between weeks 2 and 18 of pregnancy) can cause birth defects, especially to the brain.

Which statement correctly describes a feature of the rock cycle?
O Rocks are preserved through the process.
O Rocks change from one type to another.
O Different rock groups are not related to one another.
O Rocks change from one type to another in a specific order.
Answer:
The correct description of a feature of the rock cycle is:
O Rocks change from one type to another.
Explanation:
Sedimentary, metamorphic, and igneous rocks are the three main rock types. Together, they form the universal rock cycle. A sedimentary rock, for example, can change from its known state to another state by passing through crystallization, metamorphism, erosion, and sedimentation. There are no specific orders for the change. The processes that they pass through determine the resulting type.
Answer:
Rocks change from one type to another.

According to the diagram how are the three components
of a nucleotide important to the structure of DNA?
Answer:
A nucleotide of DNA is made up of three parts: a nitrogenous base, a 5-carbon sugar, and a phosphate group. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.
The phosphate group linked with deoxyribose sugar to make the framework for the nitrogenous bases. The phosphate group and sugar molecule make the DNA backbone and support it. These backbones hold nitrogenous bases and make a monomer of DNA. Nitrogenous bases make DNA stable and hold both backbones together. These bases also make DNA functional.
How can embryos be more useful than adults to show evolutionary relationships among organisms?
Select one:
Related organisms always appear identical in embryonic stages.
Adults may have mutations that are not found in embryos.
Evolutionary relationships are more easily observed in more simple organisms.
Features found in embryos may not be found in adults.
Answer:
Related organisms always appear identical in embryonic stages.
Explanation:
Embryos of organisms that have a closer genetic relationship to one another tend to look similar for a longer period of time since they share a more recent common ancestor. Thus, embryology is frequently used as evidence of the theory of evolution and the radiation of species from a common ancestor.
Can someone tell me if this is correct I need help with the percentage
Answer:
Hand = 75%
No hand = 25%
Explanation:
It's the same thing as last time. Since 3 of them are heterozygous and have 1 dominant allele, they have the dominant trait. And since one of them only has recessive alleles then it should have the recessive traits.
So the hand should have 75% and no hand has 25%.

Which of the following will most likely result if all of the primary consumers are removed from this ecosystem?
Answer:
Secondary consumers will lower in numbers and the producers (plants) will be overabundant.
Explanation:
Okay so secondary consumers eat the primary consumers and the primary consumers eat the producers (plants). If there are no primary consumers, there is no one eating the plants which will lead to the producer population growing because there's less stopping them from growing in numbers. The secondary consumers will be in trouble because the secondary consumers don't eat plants. If there are no primary consumers, the secondary consumers won't be able to eat and the numbers of secondary consumers will decrease.
