Eukaryotic chromosomes contain two general domains that relate to the degree of chromatin condensation. These two regions are _
Answer:
This question lacks options, options are: A) Heterochromatin and euchromatin
B) Uniform in the genetic information they contain
C) Separated by large sketches of repetitive DNA
D) Each void of typical protein-coding sequences of DNA
E) Void of introns.
The correct answer is A.
Explanation:
The chromatin or substance that makes up the nuclei of cells and that results from the interaction of DNA with histonic and non-histonic proteins and RNA; it can present different degrees of packing or contraction. When chromosomes are stained with chemicals that bind to DNA, densely stained regions and less densely stained regions appear. Heterochromatin are segments of the chromosome that stain strongly and remain visible, practically, during the entire cell cycle. There are few genes in these regions and therefore low transcriptional activity. They are supercondensed regions. Euchromatin are segments of the chromosome that are not visible during telophase and interphase, only in metaphase. It corresponds to regions that are less compact and in which there is a higher gene density.
which one produces proteins?
Answer:
Ribosomes are complex molecular machines in living cells that produce proteins from amino acids in a process known as protein synthesis or transformation. The process of protein synthesis is a primary function performed by all living cells.

Earth’s continents are constantly in motion because they sit on top of gigantic plates which float on Earth’s mantle. Energy from the Earth’s core creates convection currents in the molten layer, and the currents move the plates. Over extremely long periods of time, this movement creates new _______.
a.
biomes
b.
plates
c.
atmospheric layers
d.
elements
Answer:
a. biomes
Explanation:
Ecology can be defined as the scientific study of the relationship between living organisms such as plants and animals in relation to their physical and biological environment.
An ecosystem can be defined as the natural living habitats of both living and non-living organisms, in which they interact with one another. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.
Generally, the different continents on Earth are in a constant motion due to the fact that they're sitted on top of gigantic plates floating on Earth’s mantle.
Furthermore, the Earth’s core generate energy which also creates convection currents in the molten layer of the Earth, thereby, moving the plates.
Over an extremely long periods of time, the movement of these plates create new biomes.
In Ecology, a biome can be defined as a relatively distinct terrestrial region which is made up of animals, micrograms and plants, and it is typically characterized by similar environmental factors such as wind, relative humidity, rainfall, temperature, etc., irrespective (regardless) of where it occurs in the world.
There are five (5) main types of biomes and these are;
I. Forest.
II. Aquatic.
III. Desert.
IV. Grassland.
V. Tundra.

After ATP donates a phosphate group to a coupled reaction, then it becomes ADP. The ADP Group of answer choices can be recharged in an equilibrium reaction to form ATP. can be recharged in an oxidation reaction to form ATP. can be recharged with the release of energy to form ATP. is a waste product that will be broken down. can be recharged with the uptake of energy to form ATP.
Answer:
can be recharged with the uptake of energy to form ATP
Explanation:
The correct answer would be that the ADP can be recharged with the uptake of energy to form ATP.
ADP is converted to ATP within a cell when free energy is available. The free energy is stored by coupling a phosphate group to ADP to form ATP, such that:
ADP + P (inorganic) + Free Energy ------> ATP
Hence, ADP can only be recharged with the uptake of energy to form ATP, a kind of reaction generally referred to as endergonic reaction.

Speech is a dynamic process requiring precisely coordinated articulatory movements for the sequencing of sounds to ultimately produce words. What is common among children with cerebral palsy
Answer:
Speech impairment
Explanation:
Cerebral palsy children suffers speech impairment and it is the inability to produce speech sounds and this may range from mild to severe. This can include an articulation disorder, fluency disorder and voice disorder.
fluency disorder is characterized by inability to pronounce a sound or repitition of a particular sound.
voice disorder is characterized by the production of abnormal pitch or volume.
Articulation disorder in the inability to articulate words, it could include stammering.

A triplet of bases in a template strand of DNA is GAT. What would be the corresponding codon for mRNA?
СТА
CUA
CTU
CUA (This one is wrong)
I don't know why there are two CUAs, but if someone could please help. This is confusing for me. Please explain & no false answers. Thanks much in advance!
Answer:
CUA
Explanation:
Chances are your teacher accidentally put the same option twice and marked one of em incorrect. You infact selected the correct answer because CUA is correct.
DNA has 4 bases: ATGC (Apples on Trees = A - T, & Cows eat Grass = C-G)
RNA has 4 bases: AUGC (RNA lacks the base T so A binds with U instead).
So for template strand GAT, the mRNA made from this codon has complimentary pairing based on RNA so G binds with C, A binds with U, and T binds with A.
A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU
DNA is a two-stranded molecule. Each strand is a polynucleotide composed of A (adenosine), T (thymidine), C (cytidine), and G (guanosine) in a sequence.
Adenine always bonds with thymine, and guanine only bonds with cytosine. In RNA however, uracil is substituted for thymine instead. So, in transcription, adenine turns into thymine, and guanine turns into cytosine, and vice-versa.
Thus, A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU

Severe combined immunodeficiency (SCID): Group of answer choices is a result of the absence of macrophages or B cells. affects only part of the adaptive immune response. can be caused by failure of TAP transporters. is caused by the lack of T cell and B cell maturation/differentiation.
Answer:
is a result of the absence of macrophages or B cells.
Explanation:
Severe combined immunodeficiency (SCID) results due to the absence of macrophages or B cells that is responsible for the immunity of our body. Severe combined immunodeficiency (SCID) is an inherited immunodeficiency disease (PIDD) that presents in infancy results in a weak immune system that is unable to fight against even mild infections so due the absence of macrophages or B cells, the body is vulnerable to diseases.

Why do you think it is functionally important that the bones of the os coxae fuse together rather than remain independent bones
Answer:
Provides more strength.
Explanation:
It is functionally important that the bones of the os coxae fuse together rather than remain independent bones because the fusion of bones of the os coxae increases their strength and they can perform their function very well. If the fusion of bones of the os coxae did not occur and they remain independently so they can't bear the load of the body and so the function is also adversely affected.
comparison mitosis meiosis purpose ? ? number of parent cells ? ?
Explanation:
mitosis has 1 stage and meiosis had 2 stages.
Mitosis produces diploid cells (46 chromosomes) and produces 2 identical daughter cellsMeiosis produces happiness cells (23 chromosomes) and produces 4 genetically different daughter cellsAnswer:
Mitosis and meiosis are nuclear division processes that occur during cell division.
Mitosis involves the division of body cells, while meiosis involves the division of sex cells.
The division of a cell occurs once in mitosis but twice in meiosis.
Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis.
Daughter cells resulting from mitosis are diploid (46 chromosomes), while those resulting from meiosis are haploid (23 chromosomes).
Daughter cells that are the product of mitosis are genetically identical. Daughter cells produced after meiosis are genetically diverse (genes swap during division).
Mitosis has 1 parent and meiosis produces 2 types of sex cells which fuse at fertilisation.
