Answer:
Environmental conditions
macroevolutionary
Explanation:
Environmental conditions has a great affect on the survival, growth and development of organisms. If the environmental conditions are suitable for the organism so it will increase in population while on the other hand, if the environmental conditions are against the organisms so the organisms extinct from that region. The emergence, growth, and extinction of a large class such as dinosaurs is an example of a macroevolutionary pattern. Macroevolution is defined as the evolution of groups larger than an individual species.

1. A crazy dog runs 300 meters east, changes his mind and then runs 200 meters west. He then changes his mind again and runs 500 meters east. This entire trip takes 2 minutes.
a) What is the total distance traveled?
b) What is the total displacement?
c) What was the dog’s average speed?
d) What was the dog’s average velocity?
Answer:
1000 m ; 600 m east ; 8.333 m/s ` 5 m/s
Explanation:
Total distance :
(300 + 200 + 500) m = 1000 m
Total Displacement :
300 m east - 200 m west + 500 m east
100 m east + 500 m east
= 600 m east
Average speed :
Distance / time
100 m / 2 * 60 s
100 m / 120 s
= 8.333 m/s
Average velocity :
Displacement / time
600 m / 2 * 60 s
600 m / 120 s
= 5 m/s

why is person suffering from common cold can't smell properly?
Answer:
When you have a cold, the swelling causes inflammation and obstruction, which impairs your smell. The flavor of food is produced only after taste is combined with a smell, so if a stuffy nose impairs your sense of smell, it will also decrease your perception of taste.

how do the four female hormones control the menstrual cycle
Answer: The menstrual cycle is regulated by hormones. Luteinizing hormone and follicle-stimulating hormone, which are produced by the pituitary gland, promote ovulation and stimulate the ovaries to produce estrogen and progesterone.There are four major hormones (chemicals that stimulate or regulate the activity of cells or organs) involved in the menstrual cycle: follicle-stimulating hormone, luteinizing hormone, estrogen, and progesterone. hope this helps have a nice night❤️❤️❤️
Explanation:
The correct answer is A. It emphasizes that Japan had purposely deceived the United States
Explanation:
The excerpt presented belongs to toFranklin Roosevelt's speech in reference to the Pearl Harbor attack that took place in 1941 as the Japanese forces attacked one military based on Hawaii. In this speech Roosevelt states "the distance of Hawaii from Japan makes it obvious that the attack was deliberately planned" that shows from Roosevelt's perspective the attack was not spontaneous but has been planned which is emphasize with the use of "the distance of Hawaii from Japan" that show the attack followed a plan and especially the use of the word "deliberately" that means carefully considered or discussed before action, which shows the attack had been considered and planned before it occurred and therefore Japan attack on purpose to the U.S. Considering this, it can be concluded Answer:

Explanation:
how is the ruminant digestive system different than human digestive system?
background info:
Digestive system in animals is an important system in the context of digestion of ingested food into simpler forms that could be easily absorbed by the body cells.
This provides all the essential compounds needed by the body for the existence and development of the living organism. Different digestive systems have evolved according to different species, their feeding patterns, and their habitats.
answer:
Ruminant species survive only on plant matter. They are herbivorous animals.
Therefore, the digestive system of ruminants is evolved with the presence of a rumen which is a complex stomach with four different compartments.
Humans are omnivorous who depend on plant and animal matter both thus, their digestive system composes of one stomach.
This is the key difference between digestion of humans and ruminants.
hope this helped
Answer:The primary difference is that ruminants have modified their stomach into multiple compartments in order to host a very vibrant and diverse community of microorganisms. Some of these microorganisms are able to digest cellulose and produce volatile fatty acids. These volatile fatty acids are used as a source of energy by the ruminant. Propionate - a volatile fatty acid, is the only volatile fatty acid used for gluconeogenesis.
The rumimal microbe community also provides other nutrients as well but is mostly known for its role in cellulose digestion.
Ruminants have also evolved the ability to bring up a small ball of feed from their rumen to their mouth. They then masticate (chew) this ball to breakdown the fibrous material. This ability is commonly referred to as “chewing their cud” or ruminating. hope this helps have a bless day❤️❤️

What is species richness?(1 point)
the combined total of all individuals of each species in an ecosystem
the number of species in a community
the different types of species in an ecosystem
the population size of each species in a community
(Q1)An introduced species is not necessarily harmful to the environment; an invasive species has a negative effect.
(Q2) the number of species in a community
(Q3) If the location used to be too cold for non-native species, it is now warm enough to allow them to exist.
(Q4) It reduces biodiversity by reducing successful mating in native species.
(Q5) Large because it has led to several significant changes, including new invasive species and loss of natives.
Explanation:
i just did the quick check UwU
Species richness refers to the number of species in a community.
A community is a group of species living in a given ecosystem.An ecosystem refers to a particular geographic area where biotic factors (living things) and abiotic factors interact together.Species richness makes reference to the number of different species living in the same ecosystem.In conclusion, species richness refers to the number of species in a community.

(PLEASE HAS TO BE CORRECT!) Which of the following mechanisms is used to coordinate the expression of multiple, related genes in eukaryotic cells?
A) A specific combination of control elements in each gene's enhancer coordinates the simultaneous activation of the genes.
B) The genes share a single common enhancer, which allows appropriate activators to turn on their transcription at the same time.
Answer:
It's A
Explanation:
A specific combination of control elements in each genes enhancers coordinates the simultaneous activation of the genes. Its correct don't worry :)
The expression of multiple, related genes is coordinated through a single common enhancer gene that can be turned off by a single repressor, hence option b is correct.
How multiple, related genes is controlled?Multiple related genes are simultaneously turned off by a single repressor working in concert. The simultaneous activation of each gene's enhancer is regulated by a particular arrangement of regulatory elements.
In particular, there are two degrees of control over gene expression. The first way transcription is regulated is by regulating the amount of mRNA that can be generated from a given gene.
The translation of mRNA into proteins is regulated by post-transcriptional processes, which constitute the second level of regulation.
Therefore a single activator can control, the expression of multiple related genes in eukaryotes, hence option b is correct.

AP English Language and Composition and 2007 Scoring Guidelines Question 2
In your journal, complete a PASAFE + TEAR paragraph analyzing the student writer's use of refutation to build his/her own argument.
ANSWER:
In response to the essay by Scott Russel Sanders, “the belief that movement is inherently good” (Sanders). The genre is this essay is an opinionated essay throughout the essay he haves a natural tone against Rushdie even towards the end. He claims that we should root ourselves in places rather than ideas, that we should care for the earth rather than our own selfish desires. In quoting Rushdie directly and repeating his words and syntax, Sanders not only assures the reader of his careful thoughtfulness on the issue but also states his own belief that moving does nothing to rid us of the unfortunate aspects of the humanity of which we all wish to be free. Sanders and Rushdie have agreement and disagreement quotes that they want to share with others, but maybe more to themselves. But still, there is no argument in this essay, and is still respectful. The audience is for all people, as one that we all should hold as a fundamental belief of society. How can one create a new relationship with the world when they are constantly altering their place in it? The gradual movement from agreement to complete disagreement reinforces Sander’s point and respectfully refutes Rishdie’s point consequently. Yet he is still respectful towards Rushdie and admits that even though he disagrees completely with him, Rushdie articulated his views “as eloquently as anyone” (Sanders). He finishes by asserting that we must root ourselves to a specific place in order to “pay enough head and respect to where are are” (Sanders).
