The temperate leaves are thin to minimize absorption of sunlight, while the taiga leaves are specialized to store water during the dry season. C. The temperate leaves shed water during the wet season, while the taiga leaves can enter long periods of dormancy during colder weather. D. The temperate leaves grow in the spring and shed in the cold, while the taiga leaves are dark and wax-coated to prevent the tree from freezing.
Answer:
The correct answer is option D.
Explanation:
The temperate leaves grow in temperate forests found in America, Europe, and Asia. This biome comprise of trees have evergreen conifers with needle like leaves. Such leaves can endure wide change of temperature and light. Some vegetation of temperate biome are conifers such as Pine, Hemlock and other. The trees shed their leaves with the beginning of fall and new leaves are delivered in late-winter to protect from the cold.
On other hand, Taiga forest is the biggest biome on the planet. This biome contain conifers with long, slender waxy needles like leaves. These waxy leaves provide security against freezing temperature and from dying drying out. In contrast to temperate they don't sheds their leaves in winter and keep their needles throughout the entire year.
Thus, the correct answer is option D.
Answer:
D. The temperate leaves grow in the spring and shed in the cold, while the taiga leaves are dark and wax-coated to prevent the tree from freezing

In brief state what happens when a) dry apricots are left transferred to sugar solution? b) a Red Blood Cell is kept in concentrated saline solution? c) the Plasma-membrane of a cell breaks down? d) rheo leaves are boiled in water first and then a drop of sugar syrup is put on it? e) golgi apparatus is removed from the cell?
Answer:
Explanation:
(a) Dry apricots when placed in pure water swell due to osmosis and when in sugar water, they shrink again.
(b) When a Red Blood Cell is placed in concentrated saline solution exosmosis occurs and the RBCs shrink due to excess loss of water.
(c) Breaking of the plasma membrane leads to the scattering of the ceil organelles as it forms the basic supporting unit of the cell.
(d) When Rheo leaves are boiled in water first and then a drop of sugar syrup is put on it, osmosis does not occurs, due to the death of the cells of the leaf. This shows that selective permeability is property of living plasma membrane.
(e) Golgi complex helps in the package, storage and transfer of proteins synthesized by ribosomes. Thus, when ribosomes are removed the cell will not function properly

Answer:
Passive transport.
Explanation:
Osmosis occurs in the cell which is a type of passive transport. Passive transport refers to the transfer of solutes from one place to another without the expenditure or use of energy. Osmosis refers to the transfer of solutes from outside the cell into inside the cell through a semipermeable membrane which allow solutes which are small in size. This process occurs only when the concentration of solute is different inside and outside of the cell. while active transport is a type of transport which transfer solutes from one place to another with the use of energy in the form of ATP.

Neuron A communicates with neuron B. The ________ of neuron A releases a signal that activates a(n) ________ of neuron B.
Answer:
Axon terminal ; dendrite
Hope this answer correct :)
Neuron A communicates with neuron B, and the axon terminal of neuron A releases a signal that activates the receptors present on neuron B. The neurotransmitters are attached to the ligand-gated channel on neuron B.
What is nerve impulse transmission?The nerve impulse transmission takes place between two neurons, and then in this way, from the sensory organs, the message passes to the spinal cord and the brain. The synapse is formed between the two neurons, such as the presynaptic neuron that releases the neurotransmitters, and this activates the ligand-gated channel of the postsynaptic neuron. Due to this interaction, the neurons get excited and activated.
Hence, neuron A communicates with neuron B, and the axon terminal of neuron A releases a signal that activates the receptors present on neuron B. The neurotransmitters are attached to the ligand-gated channel on neuron B.

Answer:
the second one
Explanation:
there are only 2 sex linked chromosomes and that is X and Y
The true statement when describing sex-linked inheritance is ; ( B ) The alleles are found on the X and Y chromosome
The alleles responsible for reproductive inheritance from parents to offspring is contained in the X and Y chromosome of the reproductive gametes.
The female gametes contains double X chromosomes while the male reproductive gametes contains one X and one Y chromosomes. The alleles that are responsible for inheritance ( i.e. the sex of the offspring ) are contained in this chromosomes.
Hence we can conclude that The true statement when describing sex-linked inheritance is the alleles are found on the X and Y chromosome.

Answer:
Explanation:
1. Climate change is caused by changes in the earth's atmosphere in the amounts of greenhouse gases released into the air. Some scientists believe that 100% of global warming is due to humans. The largest contribution comes from burning fossil fuels because it releases carbon dioxide gas to the air, which is done by humans. Other factors that contribute to climate change include:
>Deforestation- clearing out trees affects wildlife, ecosystems, whether patterns. Forests cover 30% of the lands mass and clearing them leaves many animals without homes.
>Waste from factories- they release tonnes of toxic fumes into the air.
> Agriculture and farming- this is a surprising contributing factor to global warming. Animals produce a greenhouse gas called methane and when livestock are grazed at a large scale, the amount of methane produced is a big contributor to global warming.
Some fertilizers release nitrous oxide, which is another greenhouse gas.
2. The effects of global warming include:
>Melting glaciers- this leaves many animals without homes and it also causes a rise in sea levels which causes flooding. (that's 3 effects)
>Worsening droughts- this leaves many humans to die as they have no food or water.
>Increasing tornadoes

How does Photosynthesis relate to Cellular (aerobic) Respiration?
A. Photosynthesis breaks down glucose, Respiration builds it.
B. They are equal but opposite reactions.
C. Photosynthesis is for plants, while Respiration is for animals.
D. They are not related.
Answer: photosynthesis breaks down glucose. Hope you understand
Explanation:
Photosynthesis is related to Cellular (aerobic) Respiration in that they are equal but opposite reactions and the correct option is option B.
Photosynthesis and cellular respiration are complementary processes that are crucial for the energy flow in ecosystems. In photosynthesis, plants and some bacteria use sunlight to convert carbon dioxide and water into glucose and oxygen. This process stores energy in the form of glucose.
In cellular respiration, organisms, including plants and animals, break down glucose and other organic molecules in the presence of oxygen to release energy for cellular activities. This process consumes glucose and oxygen and produces carbon dioxide and water as byproducts.
Photosynthesis and cellular respiration are interconnected through the exchange of products and reactants. The oxygen produced in photosynthesis is used in cellular respiration, while the carbon dioxide produced in cellular respiration is used in photosynthesis. As a result, they form a continuous cycle that maintains the balance of oxygen and carbon dioxide in the atmosphere and provides energy for living organisms.
Thus, the ideal selection is option B.

(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).
