Tourists who visit the park feels good about the reintroduction of wolves in the park because it is a new animal they are seeing in the park. Environmentalists also feels good because this action is a step towards the protection of organisms present in the nature. People who live near the park does not feel good because wolf is a dangerous animal and if he escaped from the park, the lives of the people will be in danger.
Galactosemia is an inherited genetic condition. Children with this condition cannot break down the sugar galactose, which is part of lactose. Based on the pedigree chart, is this condition a dominant or a recessive disorder? Explain your reasoning.
Answer:
Recessive.
Explanation:
Galactosemia is an autosomal recessive genetic disorder. Recessive genetic disorders occur when an individual inherits a non-working gene from each parent.
There is no chart attached, so the reasoning is just common scientific knowledge. Please attach the chart so I can properly answer the question!
Answer:
It is recessive. Both parents are heterozygous for the trait, but they do not exhibit the disease themselves. If it were a dominant gene, both parents would have the disease if they carried the gene for it.

A cell biologist carefully measures the quantity of DNA in grasshopper cells growing in cell culture. Cells examined during the G1 phase of the cell cycle contained 200 units of DNA. What would be the amount of DNA in one of the grasshopper daughter cells right after cytokinesis?
Answer:
200 units
Explanation:
Cell cycle refers to the series of events that occurs throughout the division of a cell. Mitosis is the division used during cell growth. Mitosis consists of the Interphase stage and the Mitotic phase. The interphase stage is made up of the G1, S and G2 phases in that order. The genetic material (DNA) of the cell replicates during the Synthesis (S) phase.
Hence, this means that the DNA of grasshopper cells in the culture observed during the G1 phase will enter the S phase and replicate i.e. 200 units will form 400 units.
The cell go ahead to undergo nuclear division during the anaphase of the mitotic phase. Hence, each pole of the cell will contain 200units of DNA each. During Cytokinesis, the cytoplasm of the cell divides and the contents of the opposite poles becomes a new daughter cell. Each daughter cell will therefore contain 200 units of DNA each.
Question 7 of 10
A certain plant has a color that can range from green to yellow. Some plants
are very green, and some are very yellow, but most are in between. What is
most likely true about this trait?
A. The color is a Mendelian trait.
B. There are several genes that control the color.
C. There are only two alleles for color.
D. Being yellow is a recessive trait.
Answer:
B. There are several genes that control the color.
Explanation:
According to the description of the trait in this question in which the plant exhibits a wide range of colors from green to yellow, it shows that the trait for color in such plant is controlled by two or more (several) genes. This kind of inheritance is called a POLYGENIC INHERITANCE.
Polygenic inheritance is a kind of non-mendelian inheritance (does not follow the principles of Mendel) in which phenotypic traits of an organism is controlled by several genes. Each gene possess two alleles, which equally contribute to the phenotypic expression of such trait. Traits controlled by polygenes do not conform to Mendel's laws of inheritance as the offsprings exhibit a range of traits from the mixture of parental traits as stated in the question.
In polygenic inheritance, most of the offsprings exhibit the intermediate phenotype (between green and yellow) with few extremes (green and yellow) due to a combination of the genes in the parental phenotypes. Hence, based on the description in the question, there are several genes that control the color trait in the plant.
Answer: B. There are several genes that control the color.

Vanessa attempts to freeze liquid mercury. Which statements describe particle arrangement and motion that occur in mercury?
Answer:
Volume of mercury decreases due to close arrangement of particles.
Explanation:
When we freeze liquid mercury, its volume decreases and density increases from from 13.69 g/cm3 to 14.184 g/cm3 and form a solid mercury. The motion of particles stop when we freezes liquid mercury and the particles settles into a stable arrangement. If we cool the liquid mercury and the temperature reaches to -38.83 °C, then it converts from liquid into solid substance.

here are times where you will be provided with BUD dates. When you do not have access to the BUD dates, you will have to determine that date yourself. What is the appropriate BUD date for a water containing oral formulation? Not later than 14 days Not later than 30 days
Answer:
Explanation: Not later than 14 days.
Beyond Use Date (BUD) is the date after which a compounded sterile preparation may not be stored or transported. This time is calculated from the date of compounding, and it is different from expiration date. This is because the BUDs are assigned with a different approach from those applied to assigning expiration dates to manufactured drug products. Also, compounded preparations are intended for administration following short-term storage. So, the BUD is the date after which a compounded preparation shall not be used. A reliable BUD is established to ensure that the preparation has an accepted quality and purity at least until the labeled BUD.
BUD is calculated by:
Type of container in which it is packagedHow long the medication will be takenType of drugHow fast is the drug degradatedStorage conditionsDosage of the medicationNature of the drug and its degradation mechanism Potential for microbial proliferation in the preparationFor Nonaqueous Formulation, the BUD is not later than 6 months or the time remaining until the earliest expiration date of any API (Active pharmaceutical ingredient), whichever is earlier.
For Water-Containing Oral Formulation, the BUD is not later than 14 days when it is stored at controlled cold temperatures.
For Dermal and Mucosal Liquid, Semisolid Formulations/Water-Containing Topical, the BUD is not later than 30 days.

What has a greater influence on protein levels?
(1 point)
Protein degradation has a greater influence because outside factors like antibiotics can
cause it, and it is difficult to recover from.
O
Protein degradation has a greater influence because they are denatured faster than the cell
can produce them.
mRNA destroyer concentration has a greater influence because it is destroying mRNA before
proteins can even be produced.
mRNA destroyer concentration has a greater influence because mRNA is destroyed right
after the proteins are produced.
Answer:
mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced.
Explanation:
Proteins are synthesized from mRNA through the process of translation. mRNAs are first synthesized from a coding DNA template through the process of transcription. Hence, if mRNAs are destroyed, it means proteins will not be synthesized at all.
Protein not being synthesized at all means that mRNA destroyer concentration has a greater influence on protein levels than protein degradation. With protein degradation, not all the protein is degraded at once and some quantity of the protein can still be found, but with mRNA destroyer concentration, no protein can be found at all because it was not synthesized in the first place.
Differentiate between sub-cellular and acellular particles with examples
Answer:
Explanation:
Sub-cellular particles are particles smaller than the living cell and are found suspended in the cytosol (of a cell) like the nucleus, golgi complex and the mitochondria.
While acellular particles/organisms are particles that do not have a cell like the virsues, viroids and prions. They are not alive/inactive outside a living environment but become active immediately they are inside a living environment (like a cell).
Sub-cellular particles are structures that are found within a cell. These structures perform specific functions and are essential for the cell to carry out its biological processes.
Examples of sub-cellular particles include organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes. These structures are composed of both proteins and lipids and are enclosed by a membrane.
Acellular particles, on the other hand, are particles that do not possess a cellular structure and are not alive. These particles are much smaller than cells and are unable to carry out any metabolic processes.
Examples of acellular particles include viruses, prions, and viroids. These particles are composed of either DNA or RNA and can replicate themselves only within a host cell. They do not have their own metabolism and rely on the host cell for replication and survival.

Without the discovery of magnetic reversals recorded on the ocean floor, scientists
A. could not confirm the usefulness of sonar
B. could destroy the hypothasis of continental drift
C. could not provide a mechanism for moving continents
D. could explain how the seafloor was being destroyed
Answer:
C. could not provide a mechanism for moving continents
Explanation:
Magnetic reversals have the habit of causing geological displacements, since they are directly linked to the movements and distribution of tectonic plates on the planet, which are responsible for the movements of the continents. In this case,
if the discovery of magnetic reversals recorded on the ocean floor were not carried out, it would be impossible to establish its relationship with the movement of the tectonic plates, making it impossible to provide a mechanism for moving continents.
You find a new organism and are trying to determine what how it eats. You found it in a mud flat at the ocean and it has no teeth, but a very long alimentary canal. You see living examples moving through the mud very slowly. Based on all of this, you conclude that this animals is
Answer:
A Detritivore
Explanation:
A Detritivore is a heterotrophic organism that feeds on dead plant and animal materials. They could also feed through coprophagy which is nutrition obtained by feeding on feces. Worms that dwell on the soil, insects, and mollusks are examples of detritivores. Detritivores can also be found residing in aquatic environments. Crabs and Lobsters are examples of these organisms.
Detritivores have no teeth. So, they tend to suck in their food, and this food, through peristaltic actions, moves directly into the digestive tract where it is acted upon by digestive enzymes. From the observations, I made about the organism at the mudflat at the ocean, I can conclude that it is a detritivore.

Answer:
Sex hormones or hormones of the reproductive organs are certain cells in the reproductive organs that produce hormones.
The testis produces testosterone,the male sex hormone,and the ovaries produces oestrogen and progesterone, the female sex hormones.
In a sexually mature male,testosterone influences sexual behaviour, and together with FSH,regulates sperm production in the seminiferous tubules of the testes.
Sexually matured females undergo a regular 4-week reproductive or menstrual cycle during which a mature egg is released.This cycle is regulated by oestrogen and progesterone. During pregnancy, progesterone inhibits egg production (ovulation),brings about the development of the placenta and prevents the uterus from contracting....I hope this answers your question...

Help? You are studying an outcrop where the lower layer is limestone and the layer directly on top of the limestone is sandstone. Near the bottom of the sandstone layer are small, weathered pieces of limestone entirely contained within the sandstone. Explain how these pieces of limestone came to be contained within the sandstone.
Answer:
Due to mixing of particles present in the upper layer of limestone with sandstone during deposition.
Explanation:
The parent layer was limestone layer which is older than sandstone layer. This sandstone layer spreads on the limestone layer because of wind. The wind moves these sandstone from other region and their deposition occurs on the limestone layer. During deposition of sandstone, some particles of limestone which are present at the surface mixes with the sandstone so that's why in sandstone layer, small and weathered pieces of limestone are present.
