explain the structure of molar
Answer:
Molars are the biggest of all the teeth. They have a large, flat surface with ridges that allow them to chew food and grind it up. Adults have 12 permanent molars — six on the bottom and top jaw, and children have eight primary molars.

What is the probability of the parents having a daughter?
Answer:
1/ 2
Explanation:
since the parents can have only a son or a daughter
the total number of outcomes = 2
and favorable outcome = 1
probability of an event = no. of favorable Outcomes/ total number of Outcomes.
= 1/ 2

What is the role of DNA polymerase enzymes in replication?
(A) unzipping the double helix by breaking down the hydrogen bonds
(B) adding the free nucleotides to the complementary strand of DNA
(C) splitting the DNA molecule
(D)connecting the fragments on the lagging strand of DNA
Answer:
A
Explanation:
the function of DNA polymerase is to unzip the double helix structure of DNA by breaking down the weak hydrogen bond
Answer:
(B) adding the free nucleotides to the complementary strand of DNA
Explanation:
A DNA polymerase is an enzyme capable of creating new DNA molecules by sequentially adding nucleotides to the three prime (3')-end of a DNA strand. A DNA strand is a polynucleotide chain composed of a linear series of nucleotides, each consisting of a deoxyribose sugar, and phosphate, and a base (i.e., thymine, guanine, cytosine and adenine). Before a cell starts to divide, it needs first to replicate its genetic material by using DNA polymerases that duplicate the cell's DNA during the interphase (S phase). During this process (DNA replication), an enzyme known as helicase unwinds the DNA molecule, which is made up of two antiparallel strands oriented in opposite 3′-5′ directions to each other. Subsequently, each strand is used as a template for its replication through DNA polymerases that can add nucleotides (one at time) to an existing short fragment of RNA, i.e., the primer sequence, which is paired with the template DNA strand.

12. What would be the other strand of DNA?
-A T C C G A A GTC C GA G-
Answer:
TAGGCTTCAGGCTC
Explanation:
The complementary base of Adenine is Thymine in a DNA strand but it is Uracil if it's a Mrna strand
then the complementary base of cytosine is therefore guanine
Products of DNA replication
DNA replication occurs during Interphase. What Image shows the products of replication. If the parent strands are blue and the new strands are red? Click the correct box.
Answer:
The red one.
Explanation:
The red colour strands are the products of replication in which new DNA molecules are formed. The main purpose of replication is to produce extra set of DNA molecules for the new cell so that each cell receives extra molecules of DNA. Due to DNA replication, the cell has two types of DNA i.e. parent strands and new strands. The parent strands are blue in colour whereas the new strands are red in colour.

A scientist is studying some developing eggs from an ocean sample. The early embryos have divided only a few times, and all cells look identical. When the scientist carefully removes half the cells from an embryo, both clumps of cells are able to complete development, forming twins. The eggs can be identified as cnidarians. crustaceans. protostomes. deuterostomes. echinoderms.
Answer:
The correct answer is - deuterostomes.
Explanation:
Duetorstomes eggs ,During embryonic development the zygote undergoes cleavage. Cleavage results is slitting into multiple cells where ease cell has the ability to develop into a complete embryo when isolated.
Meiotic recombination produces new genetic information in sister chromatids.This Happens During prophase I. Order the stages of prophase I chronologically: ____ Diplotene.-The synaptonemal complex dissociates; homologous pairs remain attached (chiasmata).
Answer:
See the answer below
Explanation:
The various stages of propase I of meiosis I in chronological order would be
1. Leptotene
2. Zygotene
3. Pachytene
4. Diplotene
5. Diakinesis
The leptotene stage is characterized by the thickening or condensation of the genetic material in the nucleus such that 'thick thread' structures is formed.
At the zygotene stage, the thickness advances and structures can be seen as chromosomes under the microscope. Homologous chromosomes are seen pairing up (synapsis) through the formation of synaptonemal complex to form tetrads or bivalents.
At pachytene, an exchange of chromosomal segments between synapsed homologous chromosomes occur in a process known as crossing over. The exchange point along the synapsed chromosomes are known as the chiasmata. After the crossing over, homologous chromosomes begin to separate but remains joined at the chiasmata.
At diplotene, the dissolution of the synaptonemal complex occur and homologous chromosomes still held together by the chiasmata begin to repel one another. The chiasmata becomes terminalized.
At Diakinesis, chromosomal condensation is completed and the cell is conditioned to progress to metaphase I of meiosis I.
A suspension of yeast cells is being grown under anaerobic conditions such that glucose is degraded to ethanol and carbon dioxide. To follow this process by monitoring the release of CO214, at which positions in the glucose molecule would the C14 label need to be incorporated
Answer:
carbons 3 and 4
Explanation:
Alcoholic fermentation is an anaerobic (non-oxygen-requiring) pathway capable of converting one mole of glucose (C6H12O6) into two moles of ethanol (C2H5OH) and two moles of carbon dioxide (CO2), producing during this process two moles of ATP. The overall chemical reaction is as follow: C6H12O6 (glucose) >> 2 C2H5OH (ethanol) + 2 CO2. During this process (fermentation), energy is obtained from the glycolysis process by which each glucose molecule is broken down into two pyruvate molecules (2 CH3COCOO−). Pyruvic acid is an organic acid that ionizes to produce a hydrogen ion and a molecule of pyruvate. Subsequently, this pyruvate is then converted into ethanol and CO2, generating NAD+, i.e., the oxidized form of nicotinamide adenine dinucleotide or NAD, which is required for glycolysis (and therefore to produce ATP). Moreover, dismutation refers to the redox reaction by which one compound with an intermediate oxidation state converts into two compounds. In consequence, the CO2 generated during fermentation arises from the dismutation of pyruvic acid. During this process, the major source of CO2 is carbon 3 (C3) and carbon 4 (C4) of the glucose as a result of the dismutation of pyruvate, and thereby these positions in the glucose molecule would the C14 label need to be incorporated.

Respuesta corta: Produciendo un sentimiento de satisfacción.
Explanation
En el texto se hace referencia a una investigación para analizar la relación entre las redes sociales y el cerebro de los adolescentes. Para ello los investigadores utilizaron imágenes magnéticas del cerebros de los 32 adolescentes estudiados. Una vez terminaron el estudio se dan cuenta que "una estructura del cerebro, llamada núcleo accumbens, se activa más cuantos más likes tuviera una imagen". Además, el autor del texto agrega que "Esto es interesante si se tiene en cuenta que este órgano nervioso es el responsable de que experimentemos momentos de placer intensos al ganar un premio, comer helado, etc". De acuerdo a lo anterior se puede interpretar que las redes sociales influyen en el cerebro de los adolescentes debido a que produce en ellos un sentimiento de satisfacción o reconocimiento a recibir "likes" de otras personas. Además, este sentimiento se puede interpretar como aprobación por parte de las demás personas.

Which of these actions is likely to prevent the spread of pathogens in the environment?
Washing hands once a week
Coughing out loud
Touching wounds
Washing fruits
Answer:
A or D
Explanation:
Coughing out loud and Touching wounds will spread it, not prevent it, Its most likely D, because only washing your hands once a week is basically useless and will prevent little- to nothing so washing fruits is your best bet I would go with D

Explanation:
g An Hfr strain is produced when Select one: A. an F episome is transferred to a new cell. B. an F episome leaves the E. coli chromosome. C. an F episome leaves the host chromosome and removes some of the host chromosome. D. an F episome integrates into the E. coli chromosom
Answer:
A. an F episome is transferred to a new cell.
Explanation:
Hfr strains arise from the integration of the plasmid into the bacterial cell in one of several ways such as the recombination of events. Most commonly are formed by the UV-induced integration of E coil F factor. It tries to transfer a copy of the F factors as well the entire chromosome to the recipient bacterium.Explain the relationship of the structure of cell membrane molecules to the function of the cell membrane overall.
