Answer:
True
Explanation:
I will give an example. Two plants cross breeds. A pink flower and a red flower. The red flower has a gene for red color and the pink has a gene for pink color. Mix the two together and you have an offspring with two different genes, or alleles, that are either going to be mixed or the plant will be one or the other color.
Answer:
1) Basilar membrane
2) Stereocilia or hair cells
3) Nerve cells
4) Auditory
5) Temporal lobe
Explanation:
Basilar membrane: located inside of the cochlea which is located in the inner ear. This membrane separates two tubes that is filled with liquid which is also important for hearing.
Hair cells: Connected to the basilar membrane and they acts as sensory receptors which can catch movements (ripples) in the basilar membrane and pass this message to the neurons.
Nerve cells: One of the main cell types in the brain, which are responsible for signal transfer.
Auditory cortex: This part of the brain is located in temporal lobe and handles the auditory information.
Answer and Explanation:
The steps of the scientific method are
1) A question the investigator wants to answer.
2) Antecedents or Previous knowledge about the study object.
3) The goal, which is what the investigator wants to know.
4) The hypothesis that the investigator makes in order to predict what is going to happen.
5)The experiment is performed to answer the question.
6) Results achievement
7) Conclusions where the hypothesis is rejected or accepted.
In the case of the exposed example,
- Question: How does the amount of sunlight affect the extent of flower production?
- Previous knowledge and antecedents about solar radiation influencing different plant growth and flowering. Information about the species of interest. Other studies or investigations performed in relation to this question.
- Objective/Goal: To study the influence of sunlight in flowering
- Hypothesis: Too many hours of radiation affect flowering production
- Experiment: (Example)
Native species are going to be planted in the garden to observe their growth and flower production at different exposure levels to sunlight. Native species will be planted, as they are used to the environmental conditions and they do not need extra care, as a cultivated species would. More than one individual is needed to ensure their establishment. All the species will be watered according to each species needs and location. Plagues will be equally controlled.
- 3 native individuals of a herbaceous plant, 3 native individuals of a woody plant, and 3 native grass plants are located in a sunny section that receives straight sun radiation during the whole light hours.
- 3 native individuals of a herbaceous plant, 3 native individuals of a woody plant, and 3 native grass plants are located in a sunny section that receives sun radiation during half a day
- 3 native individuals of a herbaceous plant, 3 native individuals of a woody plant, and 3 native grass plants are located in a shaded section.
Plants will be grown and the flowering process will be recorded by season in relation to the number of flowers, sizes, quality, and pollinizer visitors which will reflect the amount and quality of nectar.
6 y 7. Every recorded result will be then analyzed to conclude.
Answer:
<em>B and C.</em>
Explanation:
The epidemiological triangle is an illustration of interaction among suitable hosts, disease agents, and the environment that drives successful outbreak of diseases.
In order to successfully tackle or reduce the incidence of a disease, the triangle has to be broken.
<em>In the case of malaria which is caused by plasmodium but spread through the female anopheles mosquito, one way of breaking the epidemiological triangle is to eliminate female anopheles mosquito in the environment using any possible means. This will stop the spread of the parasite and hence, the disease.</em>
<em>Another way to reduce/prevent malaria is to prevent the vector, female anopheles mosquito from getting to the host, the human populace. This can also be achieved by several possible means.</em>
Relocating the entire village to a neighbouring village might not break the epidemiological triangle as long as female anopheles mosquito still abounds. In the same vein, antibacterial drugs will not help to treat malaria. However, instructing residents on personal protective measures and controlling the vector through chemical larvicides will go a long way in breaking the triangle and reducing the incidence on the malaria disease.
<em>The correct options is B and C.</em>
Answer: the answer is B
Explanation: Yellow bone marrow is involved in the storage of fats. The fats in yellow bone marrow are stored in cells called adipocytes.
