Answer: The correct answer for the fill in the blank is A) Circulatory, immune.
Circulatory system also called cardiovascular system is a vast network of organs and vessels that allow the circulation of blood so as to transport nutrients, oxygen, other gases, and hormones to different parts of the body.
Blood contains different cells like white blood cells, red blood cells, platelets.
White blood cells ( also called leukocytes) work closely with immune system. They provide defense against pathogen ( disease causing organisms) through various ways ( like ingesting foreign material, producing antibodies to clear the antigens). By doing so, they protect us from infection and disease.
Answer;
-Crossing over and random independent assortment.
The two events that increase the genetic diversity of the daughter cells produced are crossing over and random independent assortment.
Explanation;
-During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments, which resulting to recombination that creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
-Additionally, when cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other, this results in gametes having unique combinations of chromosomes.
Questions
Answer the following questions in the essay box below.
What were the biotic and abiotic factors in the ecosystem?
List the populations in the ecosystem. Which population was the largest? The smallest?
Describe one niche in the ecosystem.
The question is about understanding a specific ecosystem. Biotic and abiotic factors form integral parts of an ecosystem, with biotic being the living organisms and abiotic the non-living aspects. Populations in an ecosystem refer to groups of the same species living together, and a niche is a species' role within its environment.
In any given ecosystem, there are both biotic and abiotic factors. Biotic factors represent the living organisms in the ecosystem, such as plants, animals, fungi, and microorganisms. Abiotic factors involve non-living aspects like sunlight, temperature, humidity, and soil quality.
Populations denote groups of the same species living together. The population size can vary, with some being larger and others smaller depending on the ecological conditions and availability of resources.
An ecosystem's niche is the role of a species within its environment, which includes its interactions with other organisms, its feeding habits, its reproduction, and its contribution to energy flow.
