How are photosynthesis and cellular respiration connected as a cycle?
Answer:
Photosynthesis is when energy, carbon dioxide and water react to produce glucose and oxygen. It is an endothermic reaction (takes in more energy than it gives off).
glucose + oxygen + (energy) → carbon dioxide + water
C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O
Respiration is the process of producing energy from glucose. It uses glucose and oxygen to give water, carbon dioxide and energy (thus making it exothermic).
carbon dioxide + water + energy → glucose + oxygen
6 CO 2 + 6 H 2 O → C 6 H 12 O 6 + 6 O 2
As you can see from the equations, they are essentially the reverse of each other.
Another difference is how they are used. Respiration occurs in the mitochondria of all living cells, whereas only plants photosynthesize.
In plants, they make their own glucose using the sun's energy, then respire to allow them to use the glucose for the energy they can use. The glucose can also be stored and used in many other ways other than in respiration.

Based on the information in the data table and the cladogram shown below, which of the following best describes the evolutionary history of lizards? (4 points)
Amniotic membrane Bipedal locomotion Hair Jaws Lack of tail Lungs
Gorilla X X X X X X
Human X X X X X X
Lamprey
Leopard X X X X X
Lizard X X X
Salamander X X
Shark X
Image depicts a cladogram with lamprey, shark, salamander, lizard, leopard, gorilla, and human represented. Shark diverges from lamprey with the introduction of jaws. Salamander diverges from shark with the introduction of lungs. Lizard diverges from salamander with the introduction of amniotic membrane. Leopard diverges from lizard with the introduction of hair. Gorilla diverges from leopard with the absence of a tail. Human diverges from gorilla with bipedal locomotion.
They are more closely related to lampreys than they are to leopards.
They evolved into a separate species as a result of the presence of an amniotic membrane.
They have jaws and lungs but lack an amniotic membrane.
They share a more recent common evolutionary ancestor with salamanders than they do with sharks. I think is D
Answer:
D. They share a more recent common evolutionary ancestor with salamanders than they do with sharks.
Explanation: Just took the test and got it correct
The cladogram shows that lizards share a more recent common evolutionary ancestor with salamanders than they do with sharks.
What is cladogram?A cladogram is a diagram in the form of a tree wgich shows the evolutionary relationship between organisms based on similarities shared in structure or function.
The cladogram given show that sharks, lizards and salamanders have a common origin but that Lizard diverges from salamander with the introduction of amniotic membrane.
Therefore, Lizards share a more recent common evolutionary ancestor with salamanders than they do with sharks.

write two examples of consumers tell whether they are herbivores omnivores carnivors or scavengers
Answers
Lion,Tiger -Carnivores
vulture- scavenger
Cow,sheep -Herbivores
Man, Pig -Omnivores
In an ecosystem, consumers are organisms that obtain their energy and nutrients by feeding on other organisms. They are a vital part of the food chain, and they come in different sizes and types.
Consumers can be classified into several categories based on what they eat. For example:
Herbivores: These are animals that consume only plants for their food. Examples include rabbits, cows, and giraffes.Carnivores: These are animals that consume other animals for their food. Examples include lions, tigers, and sharks.Omnivores: These are animals that eat both plants and animals. Examples include humans, bears, and raccoons.Scavengers: These are animals that feed on the remains of dead organisms. Examples include vultures, hyenas, and some types of beetles.Consumers play an important role in an ecosystem, as they help to transfer energy and nutrients from one level of the food chain to another. They are an integral part of maintaining the balance and stability of an ecosystem.

Apply Concepts Eventually, most people with Alzheimer's disease lose the ability to recognize common objects. Explain which lobe is affected at this point in the disease
Answer:
The right temporal lobe
Explanation:
The cerebral cortex of the brain has two sections known as hemispheres, and each hemisphere can be divided into four lobes: frontal, parietal, temporal and occipital. Alzheimer's disease is the most common cause of dementia, which is characterized by the damage of the temporal lobe. Alzheimer’s disease usually initiates in the hippocampus, which is a structure inside each temporal lobe. The temporal lobes are involved in different neuronal functions: object recognition, face recognition, perception, memory, language, emotions, etc. The right temporal lobe is mainly involved in processing visual information (i.e., face recognition, object recognition, familiar recognition).

What type of speciation occurred in the fish?
A. allopatric
B. peripatric
C. parapatric
D. sympatric
Answer:
A. allopatric
Explanation:
Allopatric speciation consists of the geographic separation of a continuous genetic background -population-, giving place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate individuals, or geological events. In this type of speciation, some barriers impede genetic interchange or flow. The populations are separated by a barrier and can not get together and mate anymore. These barriers might be geographical or ecological.
When a geographical barrier emerges, this is known as a vicariant event. Vicariance is the geographical separation of a population imposed by discontinuities in the physical environment that divides populations that originally were continuous. The process of vicariant allopatric speciation involves different steps:
• The emergence of the barrier.
• Interruption in the genetic interchange
• The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.
• Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.
• Prezigotic isolation mechanisms favored by selection once a secondary contact between the new formating species occurs.
So in the exposed example, the original population was composed of fishes living in a pond under the same environmental conditions and selective pressures.
However, with time, the pond dried, causing a decrease in water level and the emergence of a new physical barrier. The original population got separated by a piece of ground, and the original pond turned into two smaller ponds. The physical barrier is now interrupting the genetic flow between both groups.
Animals on each pond suffer from different environmental pressures to which they need to adapt. New mutations occur, leading to genetic divergence between the two separated groups. Two species emerged, red fishes and blue fishes.
