Answer:
The correct answer is -
Euglena - single-cell organism
Onion bulb - organ
Blood - tissue (connective tissue)
Explanation:
The level of organization of an organ, or organism could be cellular level, tissue level, the organ level, organ system, or a complete organism. These levels are formed by assembling the lower level of the organization.
Euglena is a single-cell eukaryotic organism found in freshwater. These organisms have a very simple level of an organism which is cellular level. The onion bulb is the organ of the onion plant composed of shortened, compressed, underground stems (tissue) that are an organ-level organization.
The blood is considered as connective tissue due to the blood cells present in the matrix called plasm thus, blood is connective tissue.

How does cytokinesis in animal cells differ from cytokinesis in plant cells?
Answer:
Cytokinesis occurs differently in animal and plant cells. In animal cells, the plasma membrane of the parent cell pinches inward along the cell's equator until two daughter cells form. In plant cells, a cell plate forms along the equator of the parent cell.

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.

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.

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.

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.
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.
Explanation:
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.

A. to pump blood through the veins and arteries of the human body.
B. to secrete waste products that are harmful to the human body.
C. to produce sex cells that join to form a developing baby.
D. to store iron that will be used to make red blood cells.
Answer:
to pump blood through the veins and arteries of the human body
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.

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.
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.
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.
