While digestive enzymes are produced in numerous parts of the digestive system, the pancreas produces the majority of them.
What is the important role of metabolism in digestive tract?In the digestive tract, digestion and absorption take place. All body cells may access the nutrients after they are absorbed, and the cells use them for metabolism.
The six actions, or functions, of the digestive system prepare nutrients for use by body cells.
The gastrointestinal tract, which was previously mentioned in this study, is a specialized sensory system.
In charge of detecting ingested glucose and relaying information to peripheral tissues or the brain to control glucose metabolism.
Therefore, In a human, the movement of glucose from the digestive tract to muscle cells is most directly a result of absorption and circulation.

Testes in man and ovary in female is a part of the reproductive organ which produce gametes, after fertilization to develop a baby, hence c is the correct option.
What are reproductive organs?
Female reproductive organs consist of the ovary which generates the ovum a female gamete that is responsible for fertilization.
Males consist of consisting of tests that generate the sperm male gamete which is responsible for fertilization.
Both organs are necessary to produce a gamete for fertilization which develops a zygote and makes the baby is developing of the cells.
Therefore, for producing sex cells ovaries and testes are important organs, hence option c is correct.

Elements such as carbon can move through the
environment and organisms in a cycle because
living and nonliving things interact in _______.
A. cells
B. species
C. organisms
D. ecosystems
Elements such as carbon can move through the environment and organisms in a cycle because living and nonliving things interact in ecosystem. The correct option is D.
What is an ecosystem?An ecosystem is made up of all the organisms and the physical environment in which they live.
These biotic and abiotic elements are linked by nutrient cycles and energy flows. Photosynthesis introduces energy into the system, which is then incorporated into plant tissue.
Healthy ecosystems clean even our own water, purify our air, keep our soil in good condition, regulate the climate, recycle nutrients, and provide us with food.
They supply raw materials and resources for pharmaceuticals and other uses. They are the foundation of all civilization and the lifeblood of our economies.
Because living and nonliving things interact in an ecosystem, elements such as carbon can move through the environment and organisms in a cycle.
Thus, the correct option is D.

What is the significance of crossing over?
Answer and Explanation:
Crossing over is the switching of genetic material (DNA), which occurs in Prophase 1.
This all happens in Meiosis, which is the process of the formation of sperm and egg cells.
The paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.

use an analogy to explain the sequence of events in the replication of DNA
Answer:
- There are three main steps to DNA replication: initiation, elongation, and termination.
- In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands.
1. The pollutants in our atmosphere have the ability to change the entire planet’s
2. is a theory that states that the increasing carbon dioxide in the atmosphere is causing the climate to warm up.
Answer:
Ans1 Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn't exist on our planet's surface. And it warms our planet and keeps temperatures habitable for our living Earth
Ans.2 The carbon dioxide theory states that, as the amount of carbon dioxide increases, the atmosphere becomes opaque over a larger frequency interval; the outgoing radiation is trapped more effectively near the Earth's surface and the temperature rises.

B)
Adults are most at risk because they have the highest exposure to environmental hazards.
C)
Elderly people are most at risk because their immune systems do not perform efficiently.
D)
Children are least at risk because they have well functioning immune systems.
E)
Adults are most at risk because they take in more pollutants relative to their size than children.
Answer: A)
Explanation:
Children are at a higher risk of suffering negative effects from environmental hazards than adults, because children do not have fully developed immune systems. In addition, children have a higher exposure to environmental hazards, because they spend more time outside, on average, than adults. Children also take in more air per unit mass than adults, which means that they also take in more pollutants relative to their size.

How does air flow when a low-pressure center occurs in the atmosphere?
Answer:
A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.
Explanation:
A hurricane passes through the Gulf of Mexico and destroys many of the coastal regions of Northwest Florida. Which of the following is a likely impact of this catastrophic event on biodiversity?
Group of answer choices
Species brought in by the storm surge will displace species native to the coastal wetlands.
Excessive salt from the storm surge will flood coastal wetlands and raise salinity to intolerant levels for the local species, causing a decrease in biodiversity
Coastal wetlands will grow exponentially with the input of nutrients from storm upwelling and biodiversity will increase in these areas.
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of habitat.
Answer:
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of habitat.
Explanation:
A hurricane destroys many coastal regions of Northwest Florida which leads to the loss of habitat of many species that lives on the coastal region of Northwest Florida. This hurricane destroy the habitat that leads to decrease in population of organisms that lives in that coastal region so we can conclude that the population of organisms decreases due to this hurricane.

Tar
Answer:
Fossil Resin
Explanation:
The type of fossilization that occurs when a sticky substance from plants captures and preserves an organism is Fossil Resin.
Fossil resins are usually trapped in the resin that some trees and plants including amber, copal, and retinite exude.
Amber is also a fossil resin. Under the right conditions, resins polymerize and turn into copal. Copal matures into amber after several million years.

where does the pollen go
Answer:
To be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination.
