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

Why are all viruses obligate parasites?
Answer:
All viruses are obligate parasites; that is, they lack metabolic machinery of their own to generate energy or to synthesize proteins, so they depend on host cells to carry out these vital functions.

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.

Out of 800 progeny of a three-point testcross (testcross for a heterozygote for all three loci) there were 16 double crossovers, whereas 80 had been expected on the basis of no interference (Hint: each double CO produces two double recombinants). The interference is:_________
a. 0.690
b. 0.310
c. 0.655
d. 0.090
e. 0.045
Answer:
a. 0.690
Explanation:
Since there are 16 double crossovers and 80 are expected to be basis of no interference. The total interference will be 0.80 based on the 800 progeny.
The video compares the key similarities and differences between mitosis and meiosis. Determine which events occur in mitosis, meiosis, or in both mitosis and meiosis. Write each event to the appropriate category. a. Chromosomes duplicate during interphase b. The first division separates homologous pairs; the second division separates sister chromatids c. A single division occurs, separating sister chromatids Homologous chromosomes pair up and form chiasmata d. Daughter cells contain recombinant chromosomes e. Process starts with a diploid cell Homologous pairs of chromosomes line up on the metaphase plate f. End result is four haploid cells that are genetically different from each other and the parent cell g. Duplicated chromosomes line up Individually on the metaphase plate in a diploid cel h. End result is two diploid cells that are genetically identical to each other and the parent cell Mitosis Melosis Both mitosis and meiosis
Answer:
Mitosis:
A single division occurs, separating sister chromatids
End result is two diploid cells that are genetically identical to each other and the parent cell
Meiosis:
The first division separates homologous pairs; the second division separates sister chromatids
Homologous chromosomes pair up and form chiasmata
Homologous pairs of chromosomes line up on the metaphase plate
Daughter cells contain recombinant chromosomes
End result is four haploid cells that are genetically different from each other and the parent cell
Mitosis and Meiosis:
Chromosomes duplicate during interphase
Process starts with a diploid cell
Duplicated chromosomes line up Individually on the metaphase plate in a diploid cell
Explanation:
Mitosis is the division of vegetative cells while meiosis involves the division of sex cells. Both divisions start with diploid parental cells but while the daughter cells in mitosis are also diploid, those of meiosis are haploid. This is why mitosis is referred to as equational division while meiosis is known as reductional division.
A cell that will undergo mitosis or meiosis would first have its genetic materials duplicated during interphase in addition to the synthesis of other important biochemicals such as proteins. Mitosis involves just a single division of the sister chromatids with two genetically identical daughter cells who are also clones of the parent cells resulting.
Meiosis, on the other hand, involves two divisions - the first one happens to separate homologous chromosome pairs while the second division separates sister chromatids just like in mitosis. During the early stage of meiosis, homologous chromosomes synapsed through the formation of a synaptonemal complex to form tetrads. Thereafter, synapsed chromosomes exchange chromosomal segments at a point known as chiasmata. All these happen at the prophase stage of meiosis I. The paired homologous chromosomes are then lined up at metaphase where they are engaged by the spindle fibers.
Meiosis II and mitosis are more or less the same with the chromosomes condensing at the prophase and the formation of metaphase plates at the metaphase. Sister chromatids are pulled apart and they migrate to the opposite poles at the anaphase and telophase.
In working with Drosphilia it is common to use a balancer stock to maintain mutations of interest. The balancer chromosomes are generally carrying multiple inversions on them. What effect would the inversions have on meiosis
Answer:
Fusion or pairing does not occur.
Explanation:
Inversions mutation leads to lowered fertility due to production of unbalanced gametes in the meiosis cell division. Chromosome inversions have no effect on mitosis, but they has affect meiosis because inversions changes the gametes which is only present in meiosis. If an inversion present is in the heterozygous condition, pairing of chromosomes cannot occur in a simple linear fashion due to change of sizes. But if the inverted chromosome segment has the proper size so it can paired with each other.

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.

Pls help me
Answer:
it was
Explanation:
The correct answer is B. Cellular respiration supplies energy to cells, but photosynthesis does not.
Which statement is correct?Photosynthesis and cellular respiration are two distinct processes that occur in living organisms, particularly plants. Here's a brief explanation of each process:
Photosynthesis: Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of glucose. It occurs in the chloroplasts of plant cells. The process involves the absorption of carbon dioxide (CO2) and the release of oxygen (O2) as a byproduct. Photosynthesis is responsible for converting solar energy into stored chemical energy.
Cellular respiration: Cellular respiration is the process by which cells break down glucose and other organic molecules to release energy in the form of ATP (adenosine triphosphate). It occurs in the mitochondria of cells, including plant cells. During cellular respiration, glucose and oxygen are consumed, and carbon dioxide and water are produced as waste products. This process provides energy for various cellular activities.
Given the descriptions above, option B is the correct statement. Cellular respiration supplies energy to cells through the breakdown of glucose, while photosynthesis is the process that converts light energy into chemical energy and produces glucose.

What is the difference between cellular respiration and gaseous exchange
Answer:
Gas exchange is the intake of oxygen and the excretion of carbon dioxide at the lung surface. Oxygen moves into the blood and carbon dioxide moves out of the blood. Cell respiration is the process that releases energy from the food

Answer:
B. Point D
Explanation:
I just took the quiz
In the given image, on point D, it is not possible to have any plant. The correct option is B.
What are the requirements of plants to grow?To grow plants require enough sunlight, carbon dioxide and water. By using all these, plant perform photosynthesis by which it can survive.
As point D in the given image has no light sources, as sunlight cannot penetrate deep into the water, it is impossible to have growing plants here.
Thus, the correct option is B.
