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.

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.

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.

Explanation:

Group of answer choices DNA sequences that are deduced by comparing many related DNA sequences are called CONSENSUS. Unlike DNA synthesis, RNA synthesis requires TRANSCRIPTION. PROMOTERS direct RNA polymerase to the initiation site. RNA synthesis complexes containing DNA, RNA, and polymerase perform TRANSLATION. RNA synthesis (tRNA, mRNA, and rRNA) takes place in complexes containing DNA, RNA, and polymerase are called TRANSCRIPTION BUBBLES. The expression of beta-galactosidase requires the induction of operons by addition of REPRESSORS.

Answer: A. The cells produced sugar and oxygen during photosynthesis

Explanation: Plants today make use of this same trait, absorbing the sun's energy and air to create food (sugar) and oxygen (as a by-product)

Answer:

b

Explanation:

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.

Explanation:

Lactose transporter are not absent from the membrane before induction. They are already present in the cell membrane. Lactose requires some transport medium, for this reason protein acts as transport medium for the lactose.

●photoreactive repair - A thymine dimer in a bacterial

●SDSA -A mismatched base pair during DNA replication

●. Photoreactive repair - A thymine dimer in a eukaryotic cell

● NHEJ repair- double strand break in G1 (cell does care about precise repair)

Answer:

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.

Given:

Brown allele (B) is dominant over the white allele (b).

It will be assumed that the alleles are not related to the X and Y chromosomes.

See attached diagram for details of the general case (for both homo-zygous and hetero-zygous parents)

For both parents hetero-zygous,

P1:

Genotype: Bb (100%)

Phenotype: brown (100%)

F1:

Genotypes : BB, Bb, bB and bb in equal proportions, i.e.

BB (25%), Bb (50%), bb (25%)

Phenotypes: 75% brown (from BB and Bb), 25% white (from bb)

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.

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.

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.

Answer:

They suffocate and choke because of the plastic waste, they also feel trapped in there and sometimes smaller animals get stuck in there

Answer:

Fish, seabirds, sea turtles, and marine mammals can become entangled in or ingest plastic debris, causing suffocation, starvation, and drowning. ... Plastic waste kills up to a million seabirds a year. As with sea turtles, when seabirds ingest plastic, it takes up room in their stomachs, sometimes causing starvation.

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.
