Answer: 1. d. algae
Explanation:
A primitive community is the ecological community which is occupied with the low diversity of biological species. The species located in this community includes simple organisms. The algae is an example of species that is expected to be found in a primitive community.
Answer:2 b. a natural recovery process
Explanation:
An ecological succession is a change in the biotic community of an ecosystem with respect to changes occurring in the non-living environment in due coarse of time, until the ecosystem attains stability. Succession is a natural recovery because even if any kind of natural or human induced destruction occurs in a region which is capable of reducing the population of living beings and destroy the physical environment. Some precursors of life will renew the growth and abundance of living species and the changes occurring in the physical environment will support the growth.
Electromagnetic forces are only attractive but gravitational forces are both attractive and repulsive.
Gravitational forces are only repulsive but electromagnetic forces are both attractive and repulsive.

Answer:
The digestive system is my favorite system! Without it you would not survive. Our digestive system is how we break down food into nutrients that feed our cells and give us energy to move, talk, grow, think, reproduce, and all the other crazy things that humans do.
Although each of the parts of the digestive system has specific and important functions, shockingly, you can survive without some of the parts. For example, morbidly obese individuals can have their stomach entirely removed in a procedure called a gastric bypass. In this surgery, the small intestine is linked directly to the esophagus thus “bypassing” the stomach. You can also live without your appendix. In fact, it sometimes negatively impacts health as it can become infected (have you ever known someone who had their appendix burst?). The appendix was thought to be a “vestigial organ” meaning that at one point in evolutionary history, we humans had a need for it, but now we don’t; however, there is recent evidence that the appendix is an important hotbed for beneficial bacteria that help us digest food.
Explanation:
I hope this helps! Brainliest is always appreciated!
Answer:
They wouldn't be able to digest the food. It wouldn't break down like it's supposed to with the digestive enzymes.
Answer:
If a foreign mountain lion species is introduced into the ecosystem then it can affect the ecosystem in any way. Lion is a top carnivore which eats the small animals present in the environment.
There are chances that the lion might substitute the other predators present in that region.
There are chances that the ecosystem may maintain the equilibrium.
The path of an egg cell after ovulation is from the ovary to the fallopian tube, then to the uterus, and if fertilized, it implants in the endometrium.
After an egg cell is released from the ovarian wall during ovulation, it first moves into the fallopian tube that sits adjacent to each ovary. The egg cell then travels down the fallopian tube towards the uterus - also known as the womb. If the egg gets fertilized by a sperm cell during its journey, it will implant itself in the endometrium, which is the inner lining of the uterus and supports the growing embryo in early pregnancy. Hence, the correct fill-in the blanks for this question is: fallopian tube; uterus; endometrium.

Answer:
Air cells of dough are filled with CO2.
Explanation:
Flour, water and yeast are important parts of bread dough. When we mix these the yeast enzyme will breakdown the satarch into simple sugars and metabolize the sugars to produce CO2 and ethyl alcohol into the existing air bubbles in dough.
Fermentation helps in producing the strong and elastin gluten to held the CO2 within the bubbles and inflate it. The more the air cell filled the more will be the bread dough rise.
Answer:
Presence of CO2 in the dough.
Explanation:
Yeast cells thrive on simple sugars. As the sugars are metabolized, carbon dioxide and alcohol.
chemical process known as fermentation.
Equation of Fermentation reaction:
C6H12O6(s) --> 2C2H5OH(aq) + 2CO2(g)
Tiny air cells fill with carbon dioxide are released into the bread dough, making it rise.
The answer is C, I just had this question-
