Answer:
1.) Sex organs
2.) DNA replication
3.) Sister chromatids
4.) Two identical daughter cells
5.) Late prophase 1
6.) Tetrads
Explanation:
Meiosis is a type of cell division that occurs in living organisms which involves the division of a single cell to produce four cells containing half the original amount of the parent genetic information. An example of organs that enter meiosis is the SEX CELLS.
Mitosis is another type of cell division that leads to the production of two daughter cells which are genetically identical to the parent cell. During interphase before a cell proceeds to division, DNA replication must occur. This is a process DNA uses to make a copy of itself during cell division.
Chromosomes are genetic material which occurs in pairs known as the SISTER CHROMATIDS
PROPHASE in the stage the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells
During late prophase 1 the pairs of homologous chromosomes come together to form two chromosomes and four chromatids, with one chromosome originating from each parent.
Once the chromosomes have formed a pair they are called TETRADS
Which of the following is true about environmental hazards to humans?
A)
Children are more at risk than adults because they take in more air per unit mass than adults.
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.

when people take a mineral and hold it up, what kind of test is that?
a) luster
b) cleavage
c) hardness
can someone plss help me??
Answer:
Luster
Explanation:
luster is the only answer that has to do with light. Luster is measured by the way a mineral reflects light.
Cleavage has to do with breaking minerals apart along certain fracture lines. Cleavage is not the answer.
Hardness is a test where one mineral is used to scratch another. The one that does the scratching is harder than the one that is scratched.

what is earth
please help me
Earth is a beautiful planet that revolves around a star called Sun, which is located in one of the arms of our Milky Way Galaxy. It is the only planet known to support life in the Solar System. Humans are the most intelligent civilization on this planet. It's blue when seen from space. Recently, Earth 29 spacecraft was able to land on this planet, after 28 unsuccessful landings of Earth series of spacecrafts. We were able to learn many things about humans, most important of these was the most spoken language of them, which they call English. According to experts, humans are not yet ready to know about our existence. It can take about 1 or 2 more centuries, until they are ready to know about us.

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.

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.

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.
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.

3. Which type of fossilization occurs when a sticky substance from plants captures and preserves an organism?
Permineralization
Mold
Fossil Resin
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.

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.
