This ration proves that the above working is correct and is dihybrid cross.
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.
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.

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.

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.
Which type of cell DOES have membrane-bound organelles?
A. eukaryotic
B. prokaryotic
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

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).

2. Which of the following best describes the genetic material a person receives from his or her father?
- 22 pairs of homologous chromosomes and an X and Y chromosome
- 22 haploid cells and an X or Y chromosome
- 23 diploid cells and an X and Y chromosome
- 22 autosomes and an X or Y chromosome
Answer:
22 autsomes and an X or y chromosome
Explanation:
Humans have 46 chromosomes. 23 from the mother and 23 from the father. The father has x and y chromosome. While the mother has two x chromosomes. 22 chromosomes each are given from both parents And the other chromosome (the 23rd) are the chromosomes for sex genes. Autosomes are all chromosomes that are not sex chromosomes. Therefore 22 autosomes are given from each parent. With reference to this questions 22 autsomes and one x or y chromosome will be given from the father.
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.
What is the purpose of mitosis?
Answer:
Mitosis creates more diploid cells by copying each chromosome and moves it to the other side of the cell.

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:
Why is the number of producer higher in food chain?
Answer:
because the plants are more thanare autotrophs, or organisms that produce their own food. ... They are at the bottom of the food chain because they are eaten by other organisms, and they don't need to eat for energy. Producers make their own food through the process of photosynthesis instead of eating organic matte
Blood leaving the right ventricle will move through pulmonary arteries, then 1 point
to the lungs for gas exchange, and then back to the left atrium. Which
blood vessel was omitted?
superior vena cava
The blood vessel that is omitted in this given situation is the superior vena cava.
What is the function of superior vena cava?The function of the superior vena cava is to carry the oxygen-poor blood from various parts of the upper body like the head, arm, chest, neck, etc.
In the process of blood migration from the heart to the lungs and then from the lungs back to the heart is carried out by pulmonary arteries.
Therefore, in this process superior vena cava is not involved.
