Answer:
A. Chloroplasts and mitochondria replicate in a similar manner as some prokaryotes
Explanation:
Endosymbiont theory deals with how eukaryotic organisms were formed from prokaryotic organisms. Prokaryotes such as Bacteria were documented as the first form of life on earth through fossil records before eukaryotes came into light.
Organelles such as Chloroplasts and mitochondria replicate in a similar manner as some prokaryotes. This supports the endosymbiont theory that present-day eukaryotic cells are descendants of a successful symbiotic relationship between a host cell and an engulfed prokaryote

Which of the following best characterizes an adaptive radiation? Which of the following best characterizes an adaptive radiation? Natural selection is particularly intense because disruptive selection occurs. A single lineage diversifies rapidly, and descendant species occupy many habitats and ecological roles. Descendant species occupy a large geographic area. Species recover after a mass extinction.
Answer:
A single lineage diversifies rapidly, and descendant species occupy many habitats and ecological roles.
Explanation:
In biology, adaptive radiation refers to a phenomenon in which organisms tend to diversify rapidly from a common ancestor and then radiate into a multitude of new organisms.
These new organisms may have to change their environment in order to survive. This change in their environment creates new challenges and may lead to the appearance of new environmental niches.

What do cells want to being in and what do cells want to keep out
Answer:
Cell membranes serve as barriers and gatekeepers. ... Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly. On the other hand, cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids.

F. Choose the odd one out from the given term and name the category to which
the others belong.
1. Haemophilia.Colour blindness, thalassaemia, night blindness
2. Gene. Chromosome. Allele, Ovule
3. Diffusion. Imbibition. Osmosis, Oxidation
4. Seed shape. Seed colour. Flower position. Inflorescence
Answer:
1. night blindness
2. Ovule
3. Oxidation
4. Inflorescence
Explanation:
1. Night blindness is odd among haemophilia, colour blindness, thalassaemia because night blindness is not an inheriditary disorder while other three are inheriditary diorder.
2. Ovule is odd among gene, chromosome, allele, ovule because ovule develops into a seed when fertilized and is not a part of genetic material DNA while the other three are part of genetic material.
3. Oxidation is odd among diffusion, imbibition, and osmosis because other belongs to the method of conduction of water and minerals by plants.
4. Inflorescence is odd among seed shape, seed colour and flower position because inflorescence is a group pf flower is flower axis while other belongs to a characteristic of a single or individual flower.
Hence, the correct answer is:
1. night blindness
2. Ovule
3. Oxidation
4. Inflorescence

The human genome project identified the sequence of base pairs in human DNA and identified several genes. Which question would least likely lead to a scientific investigation based on these findings? Answers: Are certain humans more likely to develop genetic diseases? How can DNA be used to identify criminals? Can drugs be developed to target certain genes? Should there be laws to protect DNA information?
Answer:
I believe the correct answer is "How can DNA be used to identify criminals?".
Explanation:
The question asks to pick the question that is least likely to lead to a scientific investigation based on these findings. The question states that the HGP identified sequences of base pairs in human DNA as well as many genes. The other questions were very likely to have arisen bases off of these findings. Criminal identification based on DNA is not the focus of the Human Genome Project.

How many significant figures in 20.8cm?
Answer:
[tex]\Huge \boxed{3}[/tex]
Explanation:
Significant figures include non-zero digits and in between zeros.
2 0 . 8
20.8 has 3 significant figures.
Answer:
[tex]\huge\boxed{3 \ significant \ figures}[/tex]
Explanation:
There are 3 significant figures in
2 0 . 8
According to the rules of significant figures:
=> All non-zero digits are significant.
=> Zeroes that come between 2 non-zero digits are also significant.
So, 3 significant figures in the term 20.8 cm.
Which term refers to all areas of Earth where life exists?
biosphere
biome
community
ecosystem
The term that used to represent the land, water, surface and atmosphere of the whole planet where life exists is called the biosphere. So option A is correct.
What is the biosphere?Multiple species make a population, population makes a community, the community makes an ecosystem, ecosystem makes a biome, and biome makes a biosphere.
The biospheres can be classified as:
Lithosphere: It consists of the land part of the earth. The lithosphere comprises plains, plateaus, mountains, etc.Hydrosphere: The water constituent of the earth forms the hydrosphere. It includes rivers, oceans, lakes, ponds, etc.Atmosphere: The air surrounding the earth comprising of varying gases forms the atmosphere of the earth.So biosphere is the largest unit of ecology which include the whole planet like earth in it. So option A is correct.

Una planta de flores púrpura se cruza con una planta de flores blancas, obteniéndose una descendencia en la segunda generación filial de 50 % heterocigotas, 25% homocigotas dominantes y 25% homocigotas recesivas. (el color púrpura domina sobre el blanco) Diga: ¿Qué genotipos y fenotipos tienen los padres para que se cumpla esta proporción en la segunda generación? ¿A qué la ley que corresponde? ¿Por qué los padres presentan ese genotipo y cuál es el fenotipo que expresan la segunda generación filial? Explique. Demuestre con cruces
Answer:
Los padres son homocigotas y la F1 estará formada por individuos heterocigotas
Explanation:
El cruzamiento entre un ejemplar homocigota dominante P (flores púrpura) y un homocigota recesivo p (flores blancas) para un rasgo determinado por un sólo un gen con dominancia completa producirá una generación filial F1 100% heterocigota. Por su parte, cuando cuando estos individuios cuyo genotipo es Pp se cruzan entre sí, los genotipos esperados en la F2 serán 1 (PP, homocigota dominante): 2 (Pp, heterocigota): 1 (pp, homocigota recesivo). Esta aserción corresponde a la segunda ley de Mendel, la cual es conocida como la Ley de Segregación Independiente.

Answer:
Oxygen debt is a physiological phenomenon in which a person consume oxygen at fater rate that it replaced by new oxygen molecules.
As shown in the graph, oxygen debt occurs just after the end of exercise because oxygen is consumed at faster rate during exercise that leads to increased respiration and body attempts to replace the used oxygen.
To overcome the problem of oxygen debt, a person should take rest that allows the body to replenish its oxygen supply.
