Answer:

d. Pluripotency markers

Explanation:

Pluripotency can be defined as the capacity of individual cells to differentiate into any cell type. Pluripotent transcription factors are pluripotent proteins that promote the differentiation of embryonic stem cells (ESCs) into stem/progenitor cells by inducing the expression of target genes, which are also capable of maintaining their pluripotent state. For example, SOX2, OCT4 and NANOG are pluripotent transcription factors highly expressed in ESCs in order to maintain the pluripotent state of these cells.

10. What is the difference between predation and parasitism? *

Answers

Answer:

Predation involves an indivudal creature hunting, killing, and then consuming an animal. An example of this would be a fox hunting a rabbit and then eating it. A parasite is something that can live on or inside another organism, feeding off of it without outright killing it (at least not right away). An example of a parastie would be a tapeworm.

Answer:

C) Predators typically kill their victim, while parasites mostly want to keep the victim alive for continued resources.

What are condensation nuclei?

Answers

Answer:

Cloud condensation nuclei or CCNs are small particles typically 0.2 µm, or 1/100 the size of a cloud droplet on which water vapor condenses. Water requires a non-gaseous surface to make the transition from a vapour to a liquid; this process is called condensation.

MAYBE I THINK ;)

Also called cloud condensation nuclei. Tiny particles upon whose surfaces condensation of water vapor begins in the atmosphere. Small nuclei less than 0.2 mm in radius are called Aitken nuclei; those with radii between 0.2 and 1 mm are large nuclei, while giant nuclei have radii larger than 1 mm.

What happens to the amount of energy as it moves up through an energy pyramid?
A. Some of the energy is lost.
B. Organisms double their energy as they move up the pyramid
C. Energy is transferred from the top to the bottom
D. The energy levels stay the same

Answers

Answer: some energy is lost from the pyramid, energy is transferred from bottom (producers) to top, but in decreasing amounts.

Explanation: total energy is conserved, but not necessarily within the energy pyramid, which is an open system where energy is lost from the pyramid, mainly as heat but also as sound.

Energy is transferred up the pyramid but the amount transferred at each stage is less because of losses outside the pyramid.

Explanation:

Among cattle, coat color is controlled by 2 codominant alleles, RR (producing a red coat) and WW (producing a white coat). The 2 alleles together, RW, produce a “roan” coat. The presence or absence of horns is controlled by the alleles H (hornless) and h (horned), with H completely dominant over h. show what the genotypes and phenotypes would be in both the F1 and F2 generations of a cross between RRHH x WWhh parents.

What Pattern of inheritance is that?
sex-linked
Co-dominant
Incomplete dominance
O polygenic recessive

Answers

Answer: Polygenic recessive

Explanation: Because polygenic dominance describes a relationship between the alleles of a polygenic trait where some alleles are dominant and others are recessive.

This is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).

What is Polygenic inheritance?

Polygenic inheritance can be described as the inheritance of traits that are governed by different genes and not just a single gene, and can also be referred to as non-Mendelian inheritance, where traits run like a bell. distributes the sizes and shows the different combinations such as dominant and recessive alleles.

Polygenic traits express several different phenotypes, or displayed characteristics where this inheritance is a type of incomplete dominance inheritance, where the expressed phenotype is a mixture of inherited traits.

Thus, this is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).

Explain why lamarckism is currently not a widely accepted theory

Answers

Answer:

Its not really taught in schools that much.

Explanation:

Lamarck's theory cannot account for all the observations made about life on Earth. For instance, his theory implies that all organisms would gradually become complex, and simple organisms disappear.

Lamarck’s theory of evolution, also called as theory of inheritance of acquired characters was rejected since he suggested that the acquired character which an organisms gain through its life experiences are transferred to its next generation, which is not possible since acquired characters does not bring any change to an individual’s set of genes.

Which statement is true regarding the transmission of sex-linked traits in a population?
O Males cannot carry recessive alleles for sex-linked traits.
O Males cannot express dominant alleles on the X chromosome.
O Males cannot express recessive alleles on the X chromosome.
O Males cannot pass alleles for sex-linked traits to their daughters.

Answers

Answer: none of the statements are true

Explanation: Males can have a recessive copy of a X-linked gene, and can pass that on in the X containing gamete and so pass it on to daughters, but not to male offspring. Males will express whichever allele, dominant or recessive that they carry.

What would happen if a cell couldn't make catalase?

Answers

Answer:

If hydrogen peroxide is not broken down by catalase, additional reactions convert it into compounds called reactive oxygen species that can damage DNA, proteins, and cell membranes. ... A shortage of this enzyme can allow hydrogen peroxide to build up to toxic levels in certain cells

If hydrogen peroxide is not broken down by catalase, it can be converted into reactive oxygen species, which can damage DNA, proteins, and cell membranes.

What is catalase?Catalase is an important enzyme that uses hydrogen peroxide, a non-radical ROS, as a substrate.This enzyme breaks down and neutralizes hydrogen peroxide to maintain optimal molecular levels within cells.It is also essential for cell signaling processes. The catalase enzyme breaks down hydrogen peroxide (H2O2) into water and molecular oxygen, protecting cells from oxidative damage by reactive oxygen species.Commercially available catalase is produced from Aspergillus niger by a solid-state fermentation process.Peroxidase or catalase is an enzyme of the oxidoreductase class. The peroxidase enzyme catalyzes the breakdown of hydrogen peroxide into water and molecular oxygen as shown.Catalase is a tetrameric heme protein that detoxifies H2O2 into oxygen and water.It is a metalloprotein oxidoreductase and when present in high concentrations he efficiently removes H2O2.

Bear in mind the biological definition of a species and also the appearance and distribution of the named populations of Ensatina. Which populations could be considered a species separate from E.e. eschscholtzii?

Answers

Answer:

E.e. oregonesis

E.e. platensis

E.e. xanthoptica

E.e. croceater

E.e. eschscholtzii

E.e. klaubori

Explanation:

The species mentioned above are probably separate species from E.e. eschscholtzii. this separation occurred due to geographic isolation, where each group of E.e. eschscholtzii evolved creating new species. This type of speciation is called "ring species" and refers to an evolution that is capable of providing species with extremes of variation that are not intercrossed, due to geographic isolation.

Answers

3,381 grams

Explanation:

The problem can be solved by using the formula for "Density." The formula for density is: Density (ρ) = [tex]\frac{mass}{Volume}[/tex]

Now that we know the formula, we can get the formula for the "mass."

mass = ρ x Volume

The given density above is 23 g/mL while the given volume is 147 mL. We have the values of the density and volume, thus, it is easy to solve the problem.

Let's solve.

mass = 23 g/mL x 147 mLmass = 3,381 grams

The mass of the meteorite is 3,381 grams.

Microscopes use lenses to magnify objects. A simple microscope uses only one lens; a magnifying glass could be called a simple microscope. The magnification of a simple microscope doesn't need any calculation because the single lens is usually labeled. A hand-lens, for example, might be labeled with 10x, meaning the lens magnifies the object to look ten times larger than the actual size.
