what is the difference between an alligator and a crocodile
Snout Shape: Alligators have a wide, rounded, u-shaped snout, while crocodiles have long, pointed, v-shaped snouts. ... Crocodiles are different from alligators in this sense, where both upper and lower jaws of a crocodile are the same size, exposing their teeth as they interlock, creating the look of a toothy grin.
Alligators have U-shaped faces that are wide and short, while crocodiles have thin V-shaped muzzles. When an alligator closes its mouth, you tend to see only its upper teeth. Crocodiles on the other hand flash a toothy grin with their top and bottom teeth interlacing.

The active ingredients in many pesticides are chemical compounds that kill organisms such as insects, molds, and weeds. Proponents claim that the use of pesticides improves crop yields and thus protects land and soil by reducing the conversion of forests and wetlands to cropland. Opponents of pesticide use claim that pesticides degrade water and soil quality and that other modern agricultural techniques and practices are responsible for the improved crop yields in recent years. Design a laboratory experiment to determine whether or not a new pesticide (product X) is toxic to minnows, a type of small fish.
Answer:
The active ingredients in many pesticides are chemical compounds that kill organisms such as insects, molds, and weeds. Proponents claim that the use of pesticides improves crop yields and thus protects land and soil by reducing the conversion of forests and wetlands to cropland.
Explanation:
The experiment design would be based on the hypothesis - that higher concentration of the new pesticide product X will result in more mortalities of minnows in the population.
Experiment:
In such type of experiment we required four different tanks with fresh water in each of them and 20 minnows in each as well.Tank 1 with no pesticide would be control in this experiment.concentration of the pesticide in tank 2: 0.05 %, tank 3: 0.1% and tank 4: 0.2%.number of death of minnows in each tank would be count after exposure every day.Experiment should be continue for 30 daysindependent variable: concentration of pesticidedependent variable: number of deaths of minnows each day of exposure.On the given design of the test we can determine whether or not a new pesticide (product X) is toxic to minnows, a type of small fish.

Normal red blood cells slide easily through narrow blood vessels. In sickle cell disease, many red blood cells change to a crescent shape like a slender moon. Crescent-shaped blood cells cause blockages in blood vessels. These blockages decrease the transport of oxygen. People with sickle cell disease often have sharp pains due to the lack of oxygen in parts of the body. The sickle cell version of the gene that causes sickle cell disease is recessive. Suppose that two parents with no symptoms have a child with sickle cell disease. What genes did the child inherit from the parents?
Answer:
please give me brainlist and follow
Explanation:
Normally, the flexible, round red blood cells move easily through blood vessels. In sickle cell anemia, the red blood are shaped like sickles or crescent moons. These rigid, sticky cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body.

B. To maintain biodiversity in the ecosystem through complex interactions with other animals in the area
C. To be able to make the environment safe
Answer:
The answer is B
Explanation:
A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. The ecosystem would be forced to radically change, allowing new and possibly invasive species to populate the habitat.

Describe the steps of transcription
Answer
The various steps in the transcription and translation process of protein synthesis are described below.
Explanation:
Proteins (made up of amino acids) have an important role in the various functioning process of an organism. Protein synthesis which takes place in the cells of an organism consists of two major processes: transcription (DNA to RNA) and translation (RNA to protein).
Transcription: It is the first process in protein synthesis which occurs in the cell nucleus where a single-stranded messenger RNA (mRNA) is created using a DNA strand and the genetic instructions in DNA are transferred to this mRNA. The steps in transcription are initiation, elongation, and termination. The beginning process known as initiation occurs when an enzyme RNA polymerase binds to a promoter (region of a gene) and the DNA unwinds. One of the DNA strands acts as a template and the enzyme reads the bases in the template DNA strand.
The next step is elongation, where the RNA polymerase builds a strand of mRNA by the addition of nucleotides using complementary base pairs. Here, adenine (A) in the DNA binds to uracil (U) in the RNA. Termination is the last step in which the transcription process ends when the RNA polymerase comes across a termination sequence in the gene. Thus, the completed single-stranded mRNA detaches from DNA.
Translation: It is the second process in protein synthesis which occurs in the ribosome of the cell where the genetic information in mRNA is used to create a protein from amino acids. A triplet of nucleotides is called a codon and they define amino acids. There are 64 possible codons and the codon, AUG acts as the start codon which initiates translation in addition to specifying the amino acid methionine. In the initiation step, the first amino acid in the polypeptide chain is brought by transfer RNAs (tRNAs) to bind to the start codon of mRNA. During elongation, each type of tRNAs in the cytoplasm bound to a specific codon on the mRNA template and adds the corresponding amino acid to the polypeptide chain. Stop codons (UAA, UAG, or UGA) terminate protein synthesis and release the polypeptide.

The _________ was the main opposition group to apartheid in South Africa. Founded in 1912, the group was later banned by the South African government. Group of answer choices Katanga National Congress Mau Mau National Congress African National Congress
Answer:
African National Congress.
Explanation:
The practice or system of Apartheid was one way the government of South Africa implemented to 'manage' the majority of black people. Though the whites are in minority, they wanted to stay superior. So, the practice of Apartheid gave them the 'scope' for authority, segregating the blacks from them.
The African National Congress, formerly known as the South African Native National Congress, was founded in 1912 by John Langalibalele Dube. The party's aim was to unite all the African people and bring them together as a united nation, irrespective of tribe or background. It later became the main party to oppose the Apartheid policy of the government. After a violent outcome of a peaceful protest, the South African government banned the party in April 1960. This ban was lifted in February 1990.

Neural crest cells appear on the edges of the neural tube and spread throughout the embryo, giving rise to all of the following structures except __________. Neural crest cells appear on the edges of the neural tube and spread throughout the embryo, giving rise to all of the following structures except __________. pharyngeal slits (or clefts) of invertebrate chordates some of the bones and cartilage of the skull sensory capsules in which eyes and other sense organs develop. teeth
Answer:
The correct answer is ''pharyngeal slits (or clefts) of invertebrate chordates.''
Explanation:
The neural crest is a temporary structure that develops as the neural tube closes. Its migratory capacity and subsequent distribution during development is a basic point in the general embryonic development and of most organs and structures in particular.These cells contribute to the formation of head cartilage and tooth dentin in fish embryos; and a large number of tissues and structures are formed from the migration of neural crest cells. Invertebrate chordates are animals of the Chordata phylum that have a notochord at some point in their development, but do not have a backbone. With a hollow nerve cord, neural tube. It appears by invagination of the dorsal surface; the tube is formed with a central cavity lined by ependyma; the anterior part of the neural tube gives rise to the brain. The neurenteric canal is a communication channel between the neural tube cavity and the intestine. The pharyngeal clefts (pharyngotremia), originally used for food; It is a filtering device that retains food particles that are included in mucus and transported to the intestine. In fish it already acquires respiratory function. In the ventral part, a groove is formed with cilia and bands of glands: endostyle or hypobranchial groove.

B.) going down a mountain
C.) going up a mountain
D.) a heavy rainstorm
I think it’s d but I’m not sure :’(
Drop in air pressure takes place when one goes up a mountain.
• Altitude is associated with air pressure, that is, with an elevation in altitude, there is a drop in air pressure.
• That is why when one goes up the mountain, the person feels a drop in air pressure.
• The air pressure is indicated with the help of an instrument called altimeter.
• There are two reasons of the drop in air pressure with altitude, that is, gravity and density.
• The high altitude regions like mountains are generally much colder than the regions closer to the sea due to low air pressure.
