observe the given relation and fill in the blanks cucumber: tendril citrus: meiosis: reduction division mitosis:
Answer:
citrus: thorns
mitosis: equational division
Explanation:
From the relationship:
Tendrils are thread-like appendages found in most climbing plants. They primarily function as supporting organs for climbing plants (such as cucumber) by stretching out and twinning around physical supports. The equivalence of this in citrus is the thorn.
Meiosis is a reductional cell division in which the chromosome number of the daughter cells is half of that of the other cells. Mitosis is equational division because the chromosome number of the parent cell is the same as that of daughter cells.
Which of the following statements helps support the endosymbiotic theory?
Choose 1 answer:
A
All cells contain ribosomes that conduct protein synthesis.
B
Cells contain genetic information in the form of DNA.
If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their
own.
If isolated from a plant cell, a chloroplast can survive and reproduce on its own.
Answer:
C. If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their own.
Explanation:
The endosymbiotic theory proposes that early eukaryotic cells evolved from endosymbiotic interactions among prokaryotic cells. This theory states that mitochondria and chloroplasts were once primitive bacterial cells that were ingested by large anaerobic prokaryotic cells, and then these cells benefited from living and working together. The most important lines of evidence that support this theory are that mitochondria and chloroplasts contain their own genetic material (circular DNA) and their own protein biosynthesis machinery (ribosomes).
When a cell uses fatty acids for aerobic respiration, it first hydrolyzes fats to Group of answer choices glycerol and fatty acids. glycerol and amino acids. fatty acids and sugars. sugars and glycerol.
Answer:
glycerol and fatty acids.
Explanation:
Fats as biological molecules can be used as energy sources by the cell when there is low or no carbohydrate (glucose) for use.
Fats, mainly triglycerides enter metabolic pathway in an aerobic condition where they undergo catabolism to produce glycerol and fatty acids, their monomeric units. This process leads to the synthesis of ATP (Adenosine triphosphate). In other words, fats are hydrolyzed to glycerol and fatty acids
A meiotic error occurred during gamete formation, resulting in an egg that has 24 chromosomes. If that egg is fertilized by a normal sperm, how many chromosomes will be in the zygote
Answer:
47 chromosomes
Explanation:
Meiosis is a kind of division that reduces the chromosome number of the daughter cells by half i.e. 2n - n. It occurs only in reproductive cells to produce sex cells or gametes. In humans, meiosis occurs to produce gametes (egg and sperm) that have 23 haploid chromosomes.
N.B: Somatic human cells have 46 chromosomes
According to this question, a meiotic error occurred during gamete formation, resulting in an egg that has 24 chromosomes. If that egg is fertilized by a normal sperm i.e. sperm with 23 chromosomes. A zygote that posseses (23 + 24) = 47 chromosomes will be produced.

how would you relate the new pandemic (C0vID 19) in the imbalance of ecosystem due to biodiversity loss?
Random Answer = Report
Correct Answer = Brainliest
Answer:
Due to no controlling agent for harmful microbes that causes new pandemic.
Explanation:
The new pandemic leads to imbalance of ecosystem due to biodiversity loss because the absence of antimicrobial agent causes the pandemic. The antimicrobial agent is responsible for the control of harmful microorganism so due to disturbance in the ecosystem, the biodiversity losses occurs and there is no organism which stop or control the population of the harmful organism that causes new pandemic.
This table shows the codons found in messenger RNA (attached). Using this information, what sequence of nucleotides in the template strand of DNA could code for the polypeptide sequence Val-His-Thr?
A. GUA-CAU-ACC (THIS IS WRONG)
B. GTA-CAT-ACC
C. CAT-GTA-TGG
D. CAU-GUA-UGG
Please explain, I'm very confused about this topic and I want to learn about it. No false answers or you will immediately be reported. Thanks in advance!
Answer:
A
Explanation:
The correct answer would be option A - GUA-CAU-ACC
Looking at the table of codons, for the amino acid Val, the first base (which is on the 1st column in the 6th row) is G while the second base (2nd column, 2nd row) is U. The third column can be any of U, C, A, or G (6th column, 4th row). Hence, GUA is plausible
For the amino acid His, the first base is C (1st column, 2nd row), the second is A (4th column, 4th row) while the last could be any of the 4 bases. Hence, CAU is plausible.
For the amino acid Thr, the first base is A (first column, 5th row), the second is C (3rd column, 2nd row) while the 3rth could be any of the 4 nucleotide bases. Hence, ACC is plausible.
Therefore, the correct sequence of nucleotides for Val-His_Thr would be GUA-CAU-ACC

Which type of cell adhesion is useful for anchoring cells together and defending against shear forces on tissues
Answer:
Desmosomes
Explanation:
Desmosomes are cellular structures that adhere to neighboring cells. Its function is to hold the epithelial cells together, associating the intermediate filament cytoskeletons of neighboring cells, thus forming a transcellular network with high resistance to mechanical traction. It thus allows the cells to maintain their shape and the epithelial sheet to exist in a stable form. Inside cells act as anchoring sites for intermediate rope-shaped filaments, which form a structural network in the cytoplasm providing a certain rigidity. Through these junctions the intermediate filaments of the adjacent cells are indirectly connected forming a continuous network that extends throughout the tissue.
A man with Type B blood has children with a woman with type A blood. Their children have the following blood types, A, AB, B, and O. What are the genotypes of the parents? What would be the genotypes of the parents if the offspring could only have type AB or A blood
the child has the blood type of Ab its obvious
Explanation:
only when both alleles is O, the blood group can be O. Thus both parents must have O as one allele
Thus man's genotype: BO or
[tex] { | }^{b} i[/tex]
Woman's genotype : AO or
[tex] { | }^{a} i[/tex]
When
the children can not have O blood
The children cannot have B blood
means the man have BO
[tex] { | }^{b} i[/tex]
and woman have AA
[tex] { | }^{a} { | }^{a} [/tex]
Because
if man have BB, and woman have AA
children can only have AB
if man have BB, and woman have AO
children can only have AB and B

Amal was on a picnic to Hatta with his parents and family friends. While playing, he collected some muddy water from the Wadi in his beaker, which he wanted to make pure and clean. A) What do you think will happen to the mud in his beaker if left overnight? B) What is this process called?
Answer:
See the answers below
Explanation:
A) The mud in Amal's beaker will settle down at the bottom of the muddy water if left overnight with clear water occupying the surface. This is because the particles of mud are insoluble in water and will settle down at the bottom of the muddy water if left undisturbed for a while.
B) The process is called sedimentation. The settled mud particles are referred to as the sediments and the clear water at the top can be decanted off to separate the sediment from the water.

Answer:
The correct answer is -
variation, over population and adaption.
Explanation:
Natural selection is the process to which the various species and populations are able to adapt and change according the environmental changes. It is affected by three main factors that are variation, over population and adaption.
Variation: varion is one of the factor that pushes the population to change towards the beneficial variation in the population for their survivability and reproducing theirselves.
Overpopulation: over population increases the competition amon population and there fore there resources become limited so few have to change or their ways of utilizing resources.
Adaption: Adapting the change takes place due to any situation in environmental that put stress on the population allow them to adapt according the change or they will extinct.
