BRAINLIEST: Explain the process of convection that rock in the mantle of Earth undergoes. 2-3 sentences
Answer:
Can you please help me with something?
Explanation:
Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.
The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle. The lithosphere is divided into a number of tectonic plates that are continuously being created or consumed at plate boundaries. Accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading. This hot added material cools down by conduction and convection of heat. .

Which of the following are examples of passive transport? Select all that apply.
1 exocytosis
2 membrane pumps
3 facilitated diffusion
4 diffusion
5 osmosis
Facilitated diffusion, osmosis and diffusion are examples of passive transport
WHAT IS PASSIVE TRANSPORT?
Passive transport is a kind of transport that does not require the input of energy (ATP). The examples of passive transport there is are as follows:Osmosis: Osmosis is the movement of water from a region of high concentration to a region of low concentration via a semipermeable membrane. Since, water is moving down a concentration gradient, no energy is required. Diffusion: This is the movement of molecules from a region of higher concentration to a region of lower concentration. No energy is required for this to occur as well. Facilitated diffusion: Facilitated diffusion is a kind of diffusion that occurs with the aid of transport proteins. It also does not require energy input.Therefore, facilitated diffusion, osmosis and diffusion are examples of passive transport.

I pour boiling water at 100 degrees Celsius into a cup at 50 degrees Celsius. Once the water touches the cup, the cup starts to heat up and the water starts to cool down... Eventually both the water and the cup will reach what temperature?
Answer:
75 degrees Celsius
Explanation:
Assuming that there is no heat lost to the surrounding, heat energy would move from the water to the cup until an equilibrium temperature is reached. At equilibrium, both the water and the cup would have the same temperature the sum of which would be equal to the sum of their initial temperatures.
Sum of initial temperatures = 100 + 50 = 150 degrees Celsius
At equilibrium, the temperature is divided equally; 150/2 = 75 degrees Celsius
Hence, both the water and the cup will reach 75 degrees Celsius temperature.

Which mode of inheritance results in a heterozygote having a phenotype that is distinct from both homozygotes?.
Because both alleles (of homozygotes) exist in the progeny, codominance is also known as no dominance in some circumstances (heterozygote). As a result, the phenotype generated differs from the genotypes of the homozygotes.
The dominance in which the two alleles or characteristics of the genotype (of both homozygotes) are displayed jointly in children is referred to as codominance (phenotype). In cross-breeding, there is no dominant or recessive allele. Rather, the two alleles coexist and are generated as a combination of both alleles (that each allele has the tendency to add phenotypic expression during the breeding process).
Plants with white as the recessive allele and red as the dominant allele produce blooms with pink and white patches following cross-breeding, which is an example of codominance.

prenatal kynurenine exposure in rats: age-dependent changes in nmda receptor expression and conditioned fear responding
Rationale: Levels of kynurenic acid (KYNA), an endogenous terrible modulator of alpha 7 nicotinic acetylcholine receptors (α7nAChRs) and antagonist at glutamatergic N-methyl-D-aspartate receptors (NMDARs), are expanded in the talent of patients with schizophrenia (SZ). In rats, dietary exposure to KYNA's immediately precursor kynurenine at some stage in the final week of gestation produces neurochemical and cognitive deficits in maturity that resemble these viewed in patients with SZ.
Objectives: The current experiments examined whether prenatal kynurenine publicity results in age-dependent adjustments in the kynurenine pathway (KP), expression of selected receptors, and cognitive function.
Methods: Pregnant dams have been fed unadulterated mash (progeny = ECON) or mash containing kynurenine (100 mg/day; progeny = EKYN) from embryonic day (ED) 15 to 22. Male offspring have been assessed as juveniles, i.e., prior to puberty (postnatal day [PD] 32), or as adults (PD70) for intelligence KYNA levels, α7nAChR and NMDAR gene expression, and performance on a hint worry conditioning (TFC) task.
Results: KYNA degrees have been similar between juvenile ECON and EKYN rats, whereas EKYN adults exhibited a ~3-fold amplify in intelligence KYNA relative to ECONs. NR2A expression was constantly reduced (30-40 %) in EKYN rats at each ages. Compared to ECON adults, there used to be a 50 % reduction in NR1, and a vogue toward diminished α7nAChR expression, in grownup EKYN rats. Surprisingly, juvenile EKYN rats performed considerably higher in the TFC paradigm than controls, whereas person EKYN animals confirmed the estimated deficits.
Conclusions: Collectively, our results provide evidence that KP changes in the fetal talent alter neuronal improvement and cause age-dependent results on neurochemistry and cognitive performance.

In which of the following ways is DNA replication similar to transcription?
Answer: D. Thymine is used in replication while uracil is used in transcription.
Explanation:
Genetic information is stored in double-helixes of DNA molecules (Doxyribonuclease). In replication, two daughter strands of DNA are copied from the parent strand, while in replication, instructions stored within DNA are copied into a different form, called mRNA or messenger RNA.
Nucleotides are monomers comprising DNA, a nucleic acid that along with RNA, a ribose sugar-containing nucleotide, acts as a storage molecule to encode proteins. 5-carbon deoxyribose or ribose sugar, phosphate and one of four nitrogen bases are found in nucleotides:
Adenine (A)
Guanine (G)
Cytosine (C)
Thymine (T).
Uracil (U) found in RNA
While both contain four nucleotide bases, in RNA, uracil replaces thymine... The DNA nucleotides are involved in replication while RNA nucleotides drive transcription,

The point where separation of the DNA occurs is called the replication fork.
True
False
Answer:
True
Explanation:
The point where the separation of the DNA occurs is called the replication fork. Therefore, it is true.
What is a replication fork?The DNA double helix of a cell has been unwound and split into the replication fork, which is where DNA polymerases and other enzymes can work.
DNA helicases unwind DNA at locations known as origins during DNA replication, where synthesis will begin. The replication fork, so named because the two strands of DNA seem forked as they are unzipped apart, is a structure that is created while DNA helicase proceeds to unwind the DNA.
A replication bubble is created when the circular bacteria chromosome's double-stranded DNA is opened at the point of replication. A replication fork, a Y-shaped junction where double-stranded DNA is split into two single strands, is present at each end of the bubble. Therefore, it is true.
