The mouth of the Mississippi River delta opens into the Gulf of Mexico. Sediment from the river is
pushed out into the ocean. Shipping channels in this area require regular maintenance to push
away sediment so channel depth can allow ships to travel in and out of the Mississippi River
How do you predict this area might change after 100 years with no human intervention?
If there is no human intervention for 100 years in the mouth of the Mississippi River delta, the area is likely to undergo many changes, such as the sediment buildup that would likely result in the shallowing of the shipping channels, making it difficult for ships to navigate.
What is the Mississippi River Delta?Without human intervention, the sediment buildup at the Mississippi Delta would cause the formation of new landmasses or the expansion of existing ones, and the sediment carried by the river would deposit on the ocean floor, the landscape of the delta would change, and the natural habitats in the area could also be altered in the Mississippi Delta.
Hence, the area is likely to undergo many changes, such as the sediment buildup that would likely result in the shallowing of the shipping channels, making it difficult for ships to navigate.

Meiosis only occur in what type of cells?
Answer:reproductive cells
Explanation: Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).

A mutation occurs in one of the genes that codes for the eye color of an individual. This mutation changes the color of the eye from black to dark brown. The eyesight of the individual remains normal.
What kind of mutation is this, and why?
A. Beneficial mutation; changing eye color gives an advantage for finding food.
B. Harmful mutation; changing eye color causes health problems.
C. Harmful mutation; changing eye color increases reproductive success.
D. Neutral mutation; changing eye color has no effect on vision.
Answer:
D: Neutral mutation. It says the eyesight remains normal. Therefore it cannot be harmful. Changing eye color has no effect on the ability to find food. Eye color is just an appearance.

P - Artificial active immunity
Q - Natural active immunity
Question:
In your opinion, which immunity is the best? Why?
Anyone plz help this question...?
Answer:
The correct answer would be - natural active immunity.
Explanation:
Active immunity is the immunity that includes that develops antibody by the immune system after exposure to a pathogen naturally through disease or artificially by the process of immunization. This type of immunity is a long-lasting immunity.
If the active immunity is deliberately developed by exposure of antigen to the patient is called Artificial active immunity whereas natural immunity takes place through contact with a disease-causing agent.
In my opinion, natural active immunity is best as it is a fact that natural infection almost always causes better immunity than vaccines.

How is photosynthesis and cellular similar, and how are they different?
Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.

Why do daughter cells produced from meiosis have greater variation between them than
those produced from mitosis? *
(1 Point)
A. In mitosis, the daughter cells have a random half of the chromosomes from the parent cell
B. In mitosis, the daughter cells have twice as many chromosomes as the parent cell.
C. In meiosis, the daughter cells have twice as many chromosomes as the parent cell.
D. In meiosis, the daughter cells have a random half of the chromosomes from the parent cell
Answer:
D.) In meiosis, the daughter cells have a random half of the chromosones from the parent cell.
Explanation:
In mitosis, the daughter cells have the same number of chromosomes as the parent cell, while in meiosis, the daughter cells have half the number of chromosomes as the parent. The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred.

After you finish at the store you drive back south on ashland toward your house for 1 mile you stop for gas after about 0.1 hours before you get home
Answer:
hello your question is incomplete below is the missing part
What is your velocity in miles per hour on your way to the gas
station? Hint: Remember that your starting point is 2 miles from your house to the North
answer : 10 miles/hour
Explanation:
Velocity = displacement / time
displacement = 2miles - 1 mile
time = 0.1 hour
velocity on way to gas = ( 2 - 1 ) / 0.1
= 1 / 0.1 = 10 miles/hour
what is fungi? describe some economical impotance of fungi.

He walked 5 units south and met his friend Joshua. After that, he walked 2 units east and there he bumped into his friend Ethan.
At what location on the coordinate grid did Sam meet Ethan?
OA. point (-3,5)
B. point (-1,-3)
Oc.
point (-3,-5)
O
D. point (-3,-1)
Answer:
(-1,-3) on the coordinate grid.
Explanation:
The location from where Sam started his morning walk is 3 units to the left and 2 units up from the origin. This location is indicated by the point (-3,2).
He walked 5 units south and met his friend Joshua.
So, find the point that is 5 units to the south of point (-3,2). Distances north and south on the map represent a change in the y-coordinate. Moving 5 units to the south on the map from point (-3,2) places the new location at point (-3,-3).
Sam then walked 2 units east, where he met his friend, Ethan.
So, find the point that is 2 units to the east of point (-3,-3). Distances east and west on the map represent a change in the x-coordinate. Moving 2 units to the east on the map from point (-3,-3) places the new location at point (-1,-3).
So, Sam met Ethan at the location indicated by point (-1,-3) on the coordinate grid.

Describe the causes of Weathering and Erosion here: (image 1 with grass)
Hawaii Coastal Cliffs are amongst the tallest cliffs in the world. What causes their formation? (image 2 with a bunch of water)
Based on the pattern of Erosion seen in these images, describe the causes of their formation. (image 3)
Answer:
(image 1) Weathering breaks down the Earth's surface into smaller pieces. Those pieces are moved in a process called erosion, and deposited somewhere else. Weathering can be caused by wind, water, ice, plants, gravity, and changes in temperature. As waves attack the shore, headlands are eroded, producing steep sea cliffs. The waves vigorously attack the portion of the cliff near sea level where joints, fissures, and softer strata are especially vulnerable. The cliffs are undermined and caves are formed. The three main forces that cause erosion are water, wind, and ice. Water is the main cause of erosion on Earth. Although water may not seem powerful at first, it is one of the most powerful forces on the planet.

Explanation:
1. Snapdragons can be red (RR), white (WW), or pink (RW). Cross a red snapdragon with a pink snapdragon. Give the genotype and phenotype percentages.
Answer:
RR (hom0zygous dominant) - 50%
RW (heterozygous) - 50%
Red flower - 50 %
Pink flower - 50%
Explanation:
To solve this problem, we need to use a Punnett square. A red snapdragon has a genotype of RR and a pink snapdragon has a genotype of RW.
R R
R RR RR
W RW RW
50% of the offspring would have the RR genotype (hom0zygous dominant) and 50% would have the RW genotype (heterozygous). The RR genotype results in a red flower, and the RW genotype results in a pink flower, so 50% of the offspring would be red and 50% would be pink.
