Do you think the human species is part of the Earth’s ecosystem?
Answer:
I think that humans would be part of the ecosystem because we produce carbon dioxide for plants, and without carbon dioxide, plants couldn't function. (This is just my opinion on the matter, but if this was a test question, I'd say yes.)
Explanation:
Answer:
Hmmm that's a tough question. In my opinion I believe that they are because they some of us choose to have a role in the ecosystem by helping the Earth become more "green". Maybe think about this, how did we end up here on Earth? (This might go against your science class but we ended up here because God created us all.) I don't know if this helped but I hope that it did. I apologize if it didn't.

Explain the existing problems of Agroforestry market in Pakistan
Answer:
Forest ecosystems in Pakistan are no exception and the country faces a crisis as its growing population ([ 208 million) places increasing pressure on the country's food production systems and forest resources. Effective food systems that enhance productivity, increase economic outputs, improve ecological outcomes and maintain social acceptance are needed. Agroforestry, a traditional land management system in Pakistan, offers the opportunity to meet these goals. Planting trees on private farmland provides clear ownership of any timber resource and well managed systems have great potential both to boost agriculture and reduce wood shortages.

You are trying to find which wavelength of light would allow algae to do photosynthesis the worst (you want to prevent algal growth in your pond). Describe your experiment setup:
hypothesis (1 point)
independent variable (1 point - you can choose anything)
dependent variable (1 point) and how you will measure the dependent variable (1 point)
variables you will keep constant (1 point)
Answer:
The light reactions of many algae differ from those of land plants because some of them use different pigments to harvest light. Chlorophylls absorb primarily blue and red light, whereas carotenoids absorb primarily blue and green light, and phycobiliproteins absorb primarily blue or red light. Since the amount of light absorbed depends upon the pigment composition and concentration found in the alga, some algae absorb more light at a given wavelength, and therefore, potentially, those algae can convert more light energy of that wavelength to chemical energy via photosynthesis. All algae use chlorophyll a to collect photosynthetically active light. Green algae and euglenophytes also use chlorophyll b. In addition to chlorophyll a, the remaining algae also use various combinations of other chlorophylls, chlorophyllides, carotenoids, and phycobiliproteins to collect additional light from wavelengths of the spectrum not absorbed by chlorophyll a or b. The chromophyte algae, dinoflagellates, cryptomonads (class Cryptophyceae), and the class Micromonadophyceae, for example, also use chlorophyllides. (Chlorophyllides, often incorrectly called chlorophylls, differ from true chlorophylls in that they lack the long, fat-soluble phytol tail that is characteristic of chlorophylls.) Some green algae use carotenoids for harvesting photosynthetically active light, but the Dinophyceae and chromophyte algae almost always use carotenoids. Phycobiliproteins, which appear either blue (phycocyanins) or red (phycoerythrins), are found in red algae and cryptomonads.

Macronutrients can be stored by the body for later use when it enters into the fasted state.
a. True
b. False
Answer:
a. True
Explanation:
The statement being made is true. The Fasted State is where our bodies draw from glycogen and fat reserves in order to create energy. This happens only when we do not eat that we enter into this state. The body first needs to draw all the energy it can from the glycogen stores and then once that is depleted it then begins to draw from fat stores for energy. Using all the stored macronutrients and turning them into energy to sustain the body.

Pollinization is the transference of pollen grains to the stigma. Fertilization occurs when pollen grains move to the ovary and gametes meet. Option D. 2,3,4,1
What is pollinization?
Pollinization is the pollen transference from the masculine organs to the feminine organs of the flower. It might involve the same flower or different flowers, the same plant or different plants.
What are the Feminine reproductive structures?The central structure is known as a carpel, also recognized as the pistil.The base of the carpel forms the ovary, in which the eggs are produced and where the zygote develops.The opposite extreme of the carpel is the stigma, in the superior part. The stigma is a sticky surface where the pollen grains get attached.The style is the filament structure that connects the ovary and the stigma.What are the Masculine reproductive structures?The pollen grains, or male séx cells, are produced in the stamens.The stamen has an anther where the pollen is produced, and a filament that provides support.What is fertilization?Fertilization is the gamete fusion, which involves the mature germinated pollen grain and the ovule.
During fertilization
1) The mature pollen grains are driven to the stigma of the same flower or other flowers of the species, where they stick.
2) Once in the stigma, the pollen grain germinates.
3) A thin structure named pollinic tube forms. It goes from the stigma along the style and ends in the flower ovary.
4) The pollen grains move along the tube forward to the ovary, where they meet the egg and fertilize.
5) Once in the ovary, the pollen grains get in touch with the ovule. They have double fertilization.
6) The zygote develops in the ovary.

White flower color is recessive to purple flower color in pea plants. If a pea plant has white flowers, what is
the genotype and phenotype of the pea plant
Answer:
An organism's genotype is its specific combination of alleles for a given gene. So, for example, in the pea plants above, the possible genotypes for the flower-color gene were red-red, red-white, and white-white. The phenotype is the physical manifestation of an organism's allelic combination (genotype).

The genotype and phenotype of the pea plant - pp - white flower
According to Mendel, there are two or more alleles (normally two) are responsible for the expression of a trait encoded by the gene.
One allele of the particular gene has the ability to mask the phenotypic expression of the other if present in a genotype together.The allele that masks another is called the dominant allele while the allele being masked is the recessive allele.The recessive allele express their effect only if they are present with the same allele in the genotypeIn this case, a gene that codes for flower color in pea plants is involved.The purple allele (P) is dominant over the white allele (p).It is given that the pea plant has white flower color that is a recessive allele therefore, it is clear that it has two recessive alleles p in its genotype.Thus, the genotype and phenotype of the pea plant - pp - white flower

Our ability to be conscious of some aspects of our environment while
ignoring others is called:
A. the conscious mind.
B. the two-track mind.
C. selective attention.
O D. preconscious attention.
SUBMIT
Selective attention is our ability to be conscious of some aspects of our environment while ignoring others. Therefore, the correct statement is option C.
What is selective attention?
Selective attention is the ability of our mind to be conscious of some aspects while ignoring others. In selective attention, our mind focuses on a certain aspect of the environment and filters out the rest of the aspects. Selective attention is useful as it allows one to focus only on the useful information and responds to an important stimulus in an environment.
Selective attention can be affected by various factors such as our dedication to particular interests and goals. For example, while we are driving in heavy traffic, we will only focus on the potential hazards and ignores all the other information, such as education, career, etc.
Selective attention involves top-down and bottom-up processing. Top-down processing involves the use of information, such as knowledge, goals, etc. to retain our attention, while bottom-up processing involves the use of sensory information to capture our attention.
Therefore, selective attention is our ability to focus on only certain aspects of the environment.
