The diagram below shows two locations where fossils of Mesosaurus have been found. Mesosaurus was a fresh water reptile that existed on Earth about 250 million years ago. Which statement best explains why these freshwater Mesosaurus fossils are found today in some rock layers in both South America and Africa?
Answer:
they was together at one point but because of the plants under the Continent they were separated and moved
The statement which best explains why these freshwater Mesosaurus fossils are found today in some rock layers in both South America and Africa is The remains of the Mesosaurus were carried across by predators.
Where have Mesosaurus fossils been found?
Remains of Mesosaurus, a freshwater crocodile-like reptile that lived during the early Permian (between 286 and 258 million years ago), are found solely in Southern Africa and Eastern South America. It would have been physiologically impossible for Mesosaurus to swim between the continents.
How do we know Mesosaurus was freshwater?For years, mesosaurs have been considered aquatic (water-living) animals, because they have several characteristics of species that are adapted to aquatic life, like webbed hands and feet and the presence of thickened and compact bones.

. The area of particle 1 is
2.5 mm². The area of particle 2
is 0.5 mm². The area of particle
1 is how many times as big as
the area of particle 2?
Answer:
The correct answer is - 5 times
Explanation:
Given:
area of P1 = 2.5
area of P2 = 0.5
Solution:
Let assume:
area of P1 is x times of the area of P2
then the equation would be:
=> 2.5 = x*0.5
=> 2.5/0.5 = x
=> 5 = x
Thus, area of P1 is 5 times to the area of P2

_________ is a form of spina bifida in which a saclike cyst filled with CSF protrudes through the spinal defect but does not involve the spinal cord. a. Meningomyelocele b. Meningocele c. Myelomeningocele d. Spina bifida occulta
Answer:
b. Meningocele
Explanation:
Meningocele is a congenital deformity where there is a sac protruding from the spinal column, which is not related to acute neurological conditions. Thus, meningocele is caused by a protrusion of the meninges (i.e., membranes that envelop the brain and spinal cord) and cerebrospinal fluid but without accompanying nervous tissue. About 1,500 babies each year born with this type of spinal birth defect. Moreover, spina bifida occulta is a mild type of spina bifida caused when one or more vertebrae do not fully form during pregnancy. Finally, meningomyelocele (also known as myelomeningocele) is a severe type of spina bifida caused when the spinal cord and nerves develop outside of the body.
Answer:
b. Meningocele
Explanation:
Meningocele is a form of spina bifida in which a saclike cyst filled with CSF protrudes through the spinal defect but does not involve the spinal cord.
How to get Live Imaging of the Cellular Genome via CRISPR System?
The spatiotemporal organization of chromatin structure plays a critical role in regulating lineage-specific gene expression during cellular differentiation and embryonic development, via contributing to the functional output of the genome, which can be dynamically amplified or suppressed. However, there is little known about how the genomes being modified and how their structural organization regulating function output.
Answer:
a catalytically inactive Cas9 enzyme (dCas9) is fused to fluorescent labels (e.g., GFP)
Explanation:
The CRISPR-Cas9 genome editing system consists of two parts: 1- a Caspase enzyme called 'Cas9' with catalytic activity that cuts DNA strands by hydrolyzing phosphodiester bonds, and 2-a single guide RNA (sgRNA) that directs Cas9 to target sites with complementarity to nucleotides of the sgRNA in order to edit these sequences. Using a catalytically dead Cas9 (dCas9) it is possible to repurpose the CRISPR-Cas9 system, for example, by fusing dCas9 to epigenetic enzymes for epigenome editing or by fusing dCas9 to the Green Fluorescent Protein (GFP) for imaging of the cellular genome. Thus, it is possible to use dCas9 to create a customizable DNA labeler that can be complemented with a fluorescence microscope and thus track multiple genomic loci in living cells.
Describe the kind of transport the paramecium uses to remove water from its cytoplasm. (1 point) b. Explain the relationship between the contractile vacuole activity and the environmental salt concentration. (1 point) c. Predict what would occur in the paramecium if a biological toxin blocked the activity of the contractile vacuole. (1 point) d. Justify your prediction in part C. (1 point)
Answer:
Passive transport .
Explanation:
Passive transport is a kind of transport which is used by Paramecium to remove excess water from its cytoplasm. There is a inverse relationship between the contractile vacuole activity and the environmental salt concentration because if there is salty environment, the contractile vacuole did not their function because there is difference in pressure and the water moves outside when there is salty environment. Bursting of paramecium occur if a biological toxin blocked the activity of the contractile vacuole because no excess water moves to outside environment.

The concentration of the oxygen is higher outside of the cell and the oxygen will move inside or towards the cell since it is higher in the outside and lower inside the cell and the transport is passive and it doesn't require energy.
What result allowed Dintzis to conclude that proteins are synthesized from the N terminus to C terminus
Answer:
The more newly synthesized peptides had greater levels of radiolabeled H
Explanation:
Using immature red blood cells (reticulocytes), Dintzis showed that polypeptide chains of hemoglobin were created from N-terminal to the C terminus during translation. Dintzis labeled with radioactive amino acids that were being actively translated, subsequently digested the translated proteins with trypsin and finally determined the amount of tryptic protein fragments. From this experiment, Dintzis observed that the radioactive products were concentrated in the C-terminus (i.e., labeled amino acids appeared first in the C terminal tryptic peptides), thereby showing that the direction of protein synthesis is from the N terminus to the C terminus.

Particulates can be removed from smokeslack emissions by which of the following methods?
There are three criteria that scientists use to classify kingdoms. What are they?
Answer: cell type, ability to make food, and number of cells in their body
Explanation:
Goats and sheep belong to the same family but different genera. While they often live together in the same pastures, the hybrid offspring that are occasionally produced between the two species rarely survive. When such a hybrid does survive, it is usually sterile. Which of the following best explains the mechanism that maintains reproductive isolation between goats and sheep?
a. Gene flow is prevented because the two species belong to different trophic levels and therefore do not share a food source.
b. Habitat isolation creates a prezygotic barrier between the two species.
c. The males of one species and the females of the other species are fertile at different times.
d. The two species have a different number of chromosomes, resulting in a postzygotic barrier.
Answer:
d. The two species have a different number of chromosomes, resulting in a postzygotic barrier.
Explanation:
The two species i.e. sheep and goat have different number of chromosomes that resulting in a postzygotic barrier. Sheep has 56 number of chromosomes whereas goat has 60 number of chromosomes that causes postzygotic barrier in the offspring produced from the fusion of these two species. Postzygotic barrier leads to the creation of a hybrid that is sterile and unable to produce offspring because of difference in chromosome number.
