Answer:
The correct answer is - the hippocampus.
Explanation:
Hippocampus is the part of the brain located deep in the temporal lobe that is related to memory and learning abilities. The hippocampus is present in humans and other mammals, two in numbers.
Injuries to the hippocampus will be lead to problems that are associated with a memory like recognition and identifying people or things or the ability to learn things. Direction, locations type of memories would be affected if damaged.

In a certain species of plant, flowers occur in three colors: blue, pink, and white. The genotype that produces white is ww. The presence of one W allele allows pink or blue color to occur. The B (blue) is dominant to b (pink). A pure-breeding pink plant is mated with a pure-breeding white plant. All of the F1 are blue. When the blue F1 plants are self-fertilized, the F2 plants occur in the ratio 9 blue : 3 pink : 4 white. What is the genotype of the original white parent
Answer:
Wwdd
Explanation:
The original white parent is homozygous recessive, meaning it has two copies of the w allele (ww).
What is genotype?The original white parent is homozygous recessive, meaning it has two copies of the w allele (ww). This is because white is the only phenotype produced by a homozygous recessive genotype, and there are four white plants in the F2 generation, meaning that one of the parents must have contributed a w allele to all of the F2 white offspring.
The blue F1 offspring are the result of a cross between the pure-breeding pink parent (whose genotype is Ww) and the pure-breeding white parent (whose genotype is ww). The F1 offspring therefore have the genotype Ww, and since blue is dominant, they all express the blue phenotype.
When the blue F1 plants are self-fertilized, they produce an F2 generation with a 9:3:4 ratio of blue, pink, and white offspring. This is consistent with a 9:3:4 ratio of BB, Bb, and bb genotypes in the F2 generation, since blue is dominant to pink and both are dominant to white.
In conclusion, the original white parent had the genotype ww, which is homozygous recessive and produces the white phenotype.

Is a lion a producer, herbivore, consumer or a omnivore
Answer:
Lions are primarally carnivors because they only consume meat. Herbivores are animals that only consume plant like rabbits and Ominvores are animals that consumer both like humans., so consumer
Explanation:
A lion is a consumer. In ecological terms, a consumer is an organism that obtains its energy and nutrients by consuming other living organisms.
Lions are carnivores, which means they primarily feed on other animals. They are top-level predators in their ecosystems, preying on a variety of herbivores, such as zebras, wildebeests, and antelopes.
As consumers, lions play a vital role in regulating prey populations and maintaining ecological balance in their habitats. They are not producers or herbivores since they do not engage in photosynthesis or primarily eat plants.
Additionally, lions are not omnivores, which are organisms that consume both plants and animals.

O A. Fungi
O B. Archaea
O C. Plants
O D. Bacteria
Fungi and Plants are the two types of organisms are found in the domain Eukarya. The correct options are A and C.
Thus, numerous creatures with intricate cell architecture, including a separate nucleus and membrane-bound organelles, are included in the domain Eukarya. This domain includes fungi, which include yeast and mushrooms and are recognized for their distinctive means of getting nutrients and breaking down organic materials.
Algae, trees, and flowering plants all fall under the umbrella of the eukaryotic kingdom. Their capacity to carry out photosynthesis and transform sunlight into energy defines them. Fungi and plants both share key characteristics that set them apart from Archaea and Bacteria, which are members of separate domains and have unique cellular structures and genetic make-ups.
Thus, the ideal selection is option A and C.

Which of the following circumstances is responsible for generating particulate matter?
airborne, odor-causing pathogens
gases escaping from manure piles
combustion of manure piles in hot weather
evaporation from contaminated groundwater
Answer:
combustion of manure piles in hot weather
Explanation:
A manure piles are heap of animal waste or excreta mainly the waste from horse manure and the bedding which is stored to decompose and reduce in bulk.
Particulate matter is a mixture of small particles as well as liquid droplets that causes pollution and is harmful to health.
Burning of manure piles can cause to fly the dust and the dirt in the animal manure in the air and it leads to particulate matter suspended in the air.
Animals that live on intertidal rocks often exhibit compressed or dorsally flattened bodies. this is an adadptation that protects against:______
a. sunlight
b. high temperatures
c. desiccation
d. wave shock
e. predation
Answer:
d. wave shock
Explanation:
An adaptation can be defined as a phenotypic trait that makes an organism and/or species better suited to its environment, thereby this organism/species will have more chances to survive and reproduce in such conditions. Rock-dwelling aquatic animals have different ecological, morphological and behavioral adaptations to survive in this type of environment. In this regard, it is well-known that these organisms show dorsally flattened bodies, since it is one fundamental morphological adaptation which helps them to dissipate the force of the waves.
When a strip of bark is removed all the way around the trunk of a tree, the tree dies. Explain why.
Answer:
Complete girdling (the bark removed from a band completely encircling the tree) will certainly kill the tree. The reason for damage due to girdling is that the phloem layer of tissue just below the bark is responsible for carrying food produced in the leaves by photosynthesis to the roots.

C. Is the solution outside of the cell hypertonic or hypotonic?
Please help me with this! I will mark the right answer brainliest!
Answer:
a. Water will move out of the cell
b. Shrink
c. Hypertonic solution
Explanation:
a. The scenario given shows that there is greater concentration of solutes outside the cell than the concentration of solutes inside the cell because there is 75% water inside the cell and 60% water outside the cell. So by osmotic pressure, water moves out of the cell.
b. Once the cell loses water it would shrink
c. It is an hypertonic solution because the concentration of solutes outside the cell is greater than the concentration of solutes inside the cell.

Atoms of carbon-14 are radioactive. They decay into atoms of the element nitrogen. Suppose that a sample of rock is taken from a fossil. The sample has 500 atoms of carbon-14 and 1500 atoms of nitrogen. If carbon-14 has a half-life of 5700 years, how old is the fossil? 5700 years old 11,400 years old 17,100 years old 2850 years old
Answer:
11,400 years old
Explanation:
The total number of atoms present at the beginning = number of C-14 + number of N-14 atoms.
Hence;
1500 + 500 = 2000 atoms = No
At time t, N = 500 atoms of C-14 remains
Since the half life of C-14 (t1/2) = 5700 years
N/No = (1/2)^t/t1/2
500/2000 = (1/2)^t/5700
1/4 = (1/2)^t/5700
(1/2)^2 =(1/2)^t/5700
2 = t/5700
t = 2 * 5700
t = 11,400 years old

Biochemical cycles are an intricate factor for life on earth. They provide consumers and producers with the components they need to live and grow. To a
complex ecosystem such as Earth, environmental changes such as an increase in greenhouse gases can have dramatic effects. However, not all
biochemical cycles are affected equally by such changes.
Which major cycle is LEAST negatively influenced by an increase in greenhouse gases and why?
A.Carbon cycle, because the greenhouse gas is the major component of the carbon cycle.
B.Phosphorus cycle, because it is a biogeochemical cycle and does not involve the atmosphere.
C.Oxygen cycle, because oxygen can buffer greenhouse gases by binding to it and converting it with hydrogen to water.
D.Nitrogen cycle, because the atmosphere already has very low amounts of nitrogen, and greenhouse gas converts nitrogen into nitric
oxide.
Answer:B. Phosphorus cycle, because it is a biogeochemical cycle and does not involve the atmosphere

A. Using many plants ensured that both males and females were available.
B. Using more plants made the experiments much faster.
C. Using more plants was necessary because some were unable to reproduce.
D. Using many plants gave results that supported his prediction of ratios.
Answer:
D. Using many plants gave results that supported his prediction of ratios.
Explanation:
Using more plants in any experiment, such as this one, will make the results more accurate.
By using more pea plants, Mendel's prediction was more supported by the results. A larger sample size will allow the ratios to be more reliable compared to a smaller sample size.
