What terms applies to a period in
evolutionary history when a species shows
little or no change?
Answer:
Punctuated equilibrium
Explanation:
The idea of "punctuated equilibrium" suggests that species will show little to no evolutionary change throughout their history. When evolution does occur, according to this idea, it happens sporadically and relatively quickly compared to the species' full duration on Earth.
When two aqueous solutions that differ in solute concentration are placed on either side of a semipermeable membrane and osmosis is allowed to take place, the water will Group of answer choices exhibit a net movement to the side with lower solute concentration. exhibit a net movement to the side with lower free water concentration. exhibit an equal movement in both directions across the membrane. exhibit a net movement to the side with higher free water concentration
Answer:
exhibit a net movement to the side with lower free water concentration
Explanation:
The correct answer would be that the water will exhibit a net movement to the side with lower free water concentration.
Osmosis is generally defined as the movement of water molecules through semi-permeable membranes from the region of higher water potential or lower solute concentration to the region of lower water potential or higher solute concentration.
From the definition, it becomes obvious that there would be a net movement of water between the two solutions to the side with higher solute concentration or lower free water concentration.

The structural integrity of bacteria is to peptidoglycan as the structural integrity of plant spores is to
Answer:
Lignin.
Explanation:
The structural integrity of plant spores is lignin that is present in many parts of the plant. This lignin provides hardness to the plant body which help them to stand the plant erect. If this lignin is not present in the plant body the plant will not stand erected. This lignin is present in large amount in the stem of plant body so that's why the lignin provides structural integrity to plant spores
A person with curly hair has children with a person who has straight hair. All children in the F1 generation have wavy hair. What kind of inheritance pattern explains this phenomenon? What would the F2 generation look like, i.e., what would the genotype and phenotype ratios be if two wavy haired individuals had children
Answer:
The correct answer is -
a. incomplete dominance
b. f2 = 1:2:1 = straight:wavy:curly
Explanation:
In this question, it is given that a person with curly hair and a person with straight hair has all children with wavy hair. It means that the heterozygous offspring in F1 has blended traits which means this trait shows incomplete dominance. Suppose C is curly hair c is straight hair then f1 offspring will have Cc (wavy hair)
now in F2:
cross: Cc cross with Cc
gametes: C, c
Punnett square:
C c
C CC Cc
c Cc cc
Thus, the genotype and phenotype ration would be :
genotype: 1:2:1 = CC:Cc:cc
phenotype: 1:2:1 = straight:wavy:curly

GIVE BRAINLISTA meiotic error occurred during gamete formation, resulting in an egg that has 24 chromosomes. If that egg is fertilized by a normal sperm, how many chromosomes will be in the zygote
Answer:
47 chromosomes
Explanation:
Meiosis is a kind of division that reduces the chromosome number of the daughter cells by half i.e. 2n - n. It occurs only in reproductive cells to produce sex cells or gametes. In humans, meiosis occurs to produce gametes (egg and sperm) that have 23 haploid chromosomes.
N.B: Somatic human cells have 46 chromosomes
According to this question, a meiotic error occurred during gamete formation, resulting in an egg that has 24 chromosomes. If that egg is fertilized by a normal sperm i.e. sperm with 23 chromosomes. A zygote that posseses (23 + 24) = 47 chromosomes will be produced.

Explanation:
In a two-point test cross, 36 of the offspring were recombinant types. The remaining 64 offspring were parental types. How many map units separate the two loci
Answer:
36
Explanation:
A two-point test-cross is a cross between an individual with a double heterozygote genotype and a homo-zygous recessive individual in order to determine the recombination frequency between two linked genes. In genetics, one map unit (m.u.) can be defined as the measure of the distance (i.e., genetic distance instead of physical distance) between genes for which one (1) product of meiosis in one hundred (100) is recombinant. In this case, 36 of the offspring have the recombinant phenotype, while the remaining 64 offspring are not recombinant, and therefore both genes are separated by 36 mu (64 + 36 = 100 >> 36 mu).
The distance between two genes is usually expressed in map units. In the exposed example, 36 MU separates the two loci.
----------------------------------
The map unit is used to express the distance between a pair of genes.
To interpret it, we need to consider that for every 100 meiotic products, one of them results in a recombinant product.
The genetic distance will result from multiplying the recombination frequency by 100 and expressing it in map units (MU).
To calculate the recombination frequency we will use the next formula:
P = Recombinant number / Total of individuals.
We know that
Recombinant number = 36Parental number = 64Total number of individuals = 36 + 64 = 100 individualsSo now, all we need to do is to replace the terms by their values
P = Recombinant number / Total of individuals
P = 36 / 100
P = 0.36 ⇒ Recombination frequency
Now we need to get the distance between genes, expressed in Map Units.
P = 0.36
Distance in MU = P x 100 = 0.36 x 100 = 36 MU.
So, 36 MU separates the two loci.

What can you tell about an igneous rock that has a coarse-texture?
A. It is a carbonate.
B. It probably formed in a volcanic eruption.
C. It is most likely formed underground.
D. It is extrusive.
Answer: It is most likely formed underground
An igneous rock that has a coarse texture is one that formed from slowly cooling magma deep within the Earth's crust, or from slowly cooling lava on the surface. The slow cooling allows large mineral crystals to grow, giving the rock a coarse, grainy texture.
What can the size and shape determine ?The size and shape of the mineral crystals within the rock can provide information about the rock's cooling history and the conditions under which it formed. Coarse-grained igneous rocks such as granite, gabbro, and diorite typically have crystals that are visible to the open eye, with sizes ranging from a few millimeters to several centimeters in diameter.
The composition of the rock can also be determined based on the types of minerals present in the coarse-grained texture. For example, if the rock contains primarily feldspar and quartz, it is likely a granite. If it contains mainly plagioclase feldspar and pyroxene, it is likely a gabbro.
Overall, the coarse texture of an igneous rock indicates that it cooled slowly over a long period, allowing mineral crystals to grow and form a visible grain structure. The size and composition of the crystals can provide clues about the rock's history and origin.

The lump is firm and cannot be moved, and has grown very rapidly over the past few weeks. The mass is removed surgically and the pathologist diagnoses it as a Merkel cell carcinoma. If the UV radiation to which her skin was exposed affected the Merkel cells, what other cell type sharing the same specific epidermal layer might also be affected
Answer:
Basal stem cells for keratinocytes
Explanation:
Keratinocytes are epidermal cells located in the outermost layer of the skin (i.e., the epidermis). Moreover, the cells located in the basal layer of the skin are known as basal keratinocytes or basal cells. These basal cells are proliferative cells that undergo differentiation in order to form suprabasal epidermal layers. Merkel cells are neuroendocrine cells that are located in the basal layer of the skin (scattered among basal keratinocytes), which are attached to surrounding keratinocytes by intercellular junctions called desmosomes.

The term that is used to describe the number of deer in a square kilometer of forest is population density.
What is population density?
Population density is a measure of how crowded or dispersed a population is in a particular area. It is calculated as the number of individuals of a particular species per unit of area, such as square kilometer or square mile. This measure helps to understand the concentration of individuals of a species in a given area. A high population density means there are more individuals of a species per unit area, whereas a low population density indicates fewer individuals in a given area.
Population density plays a crucial role in understanding and predicting the effects of population growth on the environment. High population density can lead to increased competition for resources such as food, water, and shelter, which can cause stress on the ecosystem. It can also lead to an increased risk of diseases and higher rates of pollution. In contrast, low population densities can lead to the extinction of species due to lack of genetic diversity and inbreeding. Understanding population density is important for conservation biology, urban planning, and resource management, among others.
