A. El átomo de Thomson se caracteriza por ser esférico, con carga positiva, con electrones partículas alfa α partícula rebotada incrustados en él
Answer:
Debido a la presencia de partículas pesadas.
Explicación:
Debido a la presencia de carga positiva en el núcleo del átomo de Thomson, las partículas alfa α rebotaron cuando chocaron con el protón porque el protón es una partícula pesada y la presencia de neutrón la hace más pesada. Debido a la presencia de partículas pesadas en el núcleo, las partículas alfa no pueden atravesarlo. Solo puede pasar a través del átomo de Thomson donde hay un espacio vacío en el átomo.

Climate change has begun to affect insects as food resources have started disappearing . The monarch butterfly and the queen butterfly have to compete for the same food source . This is an example of____competition.
A. Co-species
B. Intraspecies
C. Interspecies
D. Habitat
Answer:
B.
Explanation:
In an ecological environment living things of different or same species compete with each other for the limited resources available. It is a symbiotic interaction between these living things.
There are two types of competition between these living beings- intraspecific and interspecific. In the given scenario, it is an intraspecific competition between the monarch butterfly and the queen butterfly.
Intraspecific competition is a competition between two living beings of the same species.
The monarch butterfly and the queen butterfly both belong to the same species- danaus.
Therefore, option B is correct.

Genetic variation _____. Group of answer choices is created by the direct action of natural selection always arises in response to changes in the environment must be present in a population before natural selection can act upon the population tends to be reduced when diploid organisms produce gametes
Answer:
It must be present in a population before natural selection can act upon the population.
Explanation:
Genetic variation refers to the variations that exists in the DNA of the individuals. These variations are caused mainly by mutation and genetic recombination of the DNA. It helps in the process of evolution. Genetic variations helps in building the mechanisms of change that helps in the process of evolution. Genetic variation is caused highly because of process of sexual reproduction. The offspring exhibit various genetic variation.
After a copper smelter begins operation, local downwind populations of plants begin to adapt to the resulting air pollution. Scientists document, for example, that the acid tolerance of several plant species has increased significantly in the polluted area. This is an example of
Answer:
Adaptation.
Explanation:
Adaptation occurs when the acid tolerance of several plant species has increased significantly in the polluted area. The main reason for this tolerance is the change in the genetic makeup or mutation occurs in the cell due to the exposure of DNA to the chemicals of the environment that cause pollution. The plant adopt the environment by producing certain chemicals that cancel the effects of pollutants and as a result, the plant survive.
Describe the connection between the digestive and circulatory systems (in detail)
Answer:
Explanation:(1) Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go. (2) Filters out waste from food and pushes it through intestines and out the body (and you know how and where it gets out).

Interferons Interferons reduce macrophage chemotaxis to the infection. interfere with viral replication. prevent viruses from entering a cell. bind to viruses and destroy them. prevent viruses from leaving a cell.
Answer:
interfere with viral replication
Explanation:
Interferons (IFNs) are proteinous molecules, which are part of the innate immune system of our body. Interferons are produced in response to viral infections and they often specialize in preventing the virus pathogen from replicating or multiplying in the host cell.
As their name implies, INTERFERONS interfere with the replication of viral pathogens, hence, preventing the virus from further invading the host cell. This is done at the innate immunity level.

A hybrid offspring of a male lion and a tigress is a _________.
Plz answer I will add you as brainlest
Answer:
Such offspring are called hybrid offspring. Furthermore; within such hybridization process, if male is a lion and female is a tiger (tigress) then the hybrid offspring is termed as a liger. Vice-versa; if the male is a tiger and the female is a lion (lioness) then the hybrid offspring is called a tigon.
Answer:
Liger
Explanation:
what do you mean by photo synthesis?
Answer:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Explanation:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities.

Which structure is found in the cytoplasm of
a typical plant cell?
A.vacuole
B. cell wall
C.chloroplast
D.cell membrane
Answer:
Explanation:
D
The structure that is found in the cytoplasm of plant cell is vacuole. The correct option is A.
What is vacuole?A vacuole is a cell organelle that is membrane-bound. Vacuoles are relatively tiny in animal cells and help to sequester waste material.
Vacuoles in plant cells aid in keeping water balance. A single vacuole can sometimes take up the majority of the interior space of a plant cell.
Within the cytoplasm of plant cells, there are also large, fluid-filled vesicles known as vacuoles.
Vacuoles typically make up about 30% of the volume of a cell, but they can fill up to 90% of the intracellular compartment.
Vacuoles are used by plant cells to regulate their size as well as turgor pressure.
Vacuole is a structure found within the cytoplasm of plant cells.
Thus, the correct option is A.

why is it important for plant's to store food?
Answer:
Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesis less. ... When they have extra food they store it in their seeds and when the seed grows it gets it's food from the plant until the plant is able to photosynthesis and produce its food.
Answer:
It's important for plants to store food, as food is a source of nutrition, which is necessary for survival. Rather than just eating the food, storing it is a good way to ensure nutrients during droughts or other harsh conditions that make it hard to find food.
Explanation:
To melt the ice during the winter season, road crews often put sand and salt solutions on the roadways to help melt the snow and ice. The plants that live close to the road often die or wilt after this procedure. Using your knowledge of osmosis and plant structures, which type of solution would cause this to happen to plant cells? Group of answer choices
Answer:
The missing answer choices are:
a. hypotonic
b. isotonic
c. osmosis
d. hypertonic
The correct option is d. hypertonic
Explanation:
A hypertonic solution has a higher concentration of solutes than the concentration of solutes present inside the plant. As there is a difference in concentration between the inside and the outside of the plant, the plant loses water in an attempt to balance the difference. As a result, there is an excessive loss of water that dehydrates the plant and kills it.
Please help it’s biology!!!!!!
Answer:
25%
Explanation:
If a parent is heterozygous, it has 2 difterent alleles. Both parents are heterozygous for blood type A, so the genotype is AO. A masks the O because A is dominant over O, so A is the blood type.
Create a punnett square to find possible offspring
AA = Blood type A
AO = Blood type A
OO = Blood type O
There is 1 child out of 4 that have blood type O. So to find the percentage divide 1 and 4 and multiply by 100.
1÷4×100 = 25
