Answer:
New leaves appear on a tree in spring. - NO
An amoeba divides in half. - YES
A bean plant produces seeds in long pods. - YES
Pollen grains are released from a flower. - YES
A sea star produces a new arm after losing one to a predator. - NO
Explanation:
The appearance of new leaves has nothing to do with reproduction but rather regeneration.
An amoeba dividing in half is a form of reproduction known as asexual. Binary fission is a reproductive process in which an organism divides into two and each half develops into new independent organisms.
A bean plant producing seed is part of the reproductive process. After fertilization, the ovule of a flower becomes the seed. A seed in itself is a ripened fertilized ovule.
The release of pollen grains from the anther of a flower to the stigma of a compatible flower in the same or different individuals plants is known as pollination. Pollination is a reproductive process similar to fertilization.
A sea star producing a new arm after losing one to a predator is a regeneration process rather than a reproductive process.

Describe how genetic engineering can improve human health.
Answer:
Genetic engineering is the change of a combination of genes. It can change how someone can look or discover a deathly disease that they can change into something not so deathly. If a family has a history of cancer, scientists can alter it to make it less easy to get.

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.

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.
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.

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
Why are NADH and FADH2 necessities in the electron transport chain?(1 point)
They power the electron transport chain.
They power the electron transport chain.
They remove electrons from the electron transport chain.
They remove electrons from the electron transport chain.
They move down the electron transport chain.
They move down the electron transport chain.
They move electrons to the electron transport chain.
NADH and FADH2 are necessities in the electron transport chain because they power the chain by moving electrons into it.
NADH and FADH2 are both generated at the initial stages of respiration (the Kreb's cycle), a process during which food materials are broken down to generate energy. NADH is generated from NAD+ as a result of the addition of electrons while FADH2 is generated from FAD also due to the addition of electrons.
Once generated, both compounds get transferred into the innermost membrane of the mitochondrion where they travel down the electron transport chain, donating their electrons in the process and creating an electrochemical gradient to generate ATP.
Without NADH and FADH2, there will not be electrons to power the electron transport chain and the generation of ATP would become impossible.
More about the electron transport chain can be found here: https://brainly.com/question/13975046
Answer:
The correct answer is They move electrons to the electron transport chain.
