What would most likely happen to a native predator species if a nonnative predator species were introduced to an area?
A. The native species would force the nonnative species out of the community
B. The native species population would decrease because the nonnative species would be competing for food sources.
C. The native species population would increase because the nonnative species would introduce new food sources.
D. The native species would outcompete the nonnative species.
Answer:
B. The native species population would decrease because the nonnative species would be competing for food sources.
Explanation:
This question is describing the effect of invasive species. Invasive species are foreign species i.e. not native to a habitat or area, introduced into the area with the ability to outcompete and negatively affect the native species of that area.
Invasive species compete with the native species for food, space, mate etc., and tend to outgrow them. Hence, if a nonnative predator (invasive) species were introduced to an area, the native predator species in that area would decrease because the nonnative species would be competing for food sources.

4. Describe an observation you made today and an inference you can make from that observation.
Answer:
my my teacher gives my class and I a mystery box for us to observe what's inside that box it was closed, as we was trying to know what's inside that box we were looking and thinking what does it sounds like, but my friend next to me says it sounds like a stapler and my other friend said it's not very heavy, as we were we said we could take another box just like that identified box and put a stapler since it sounds like a stapler and it's not that heavy as we know staplers are not that heavy. well we did that we check and our activity shows that the mystery box it slides and appear to be flat and all the box it slides in appear to be flat so that's the same thing as our box and the mystery box and we were looking at how does it sound when we close the box and everything we were checking how does it sound as we are observed that the mystery box it makes a metallic song when it strikes the side of the box an hour box the stapler makes a thudding sound when it strikes the side of the box and we also checked if the mass of the box was the same but it wasn't the mystery box was 270 g and our box was much more heavier which is 410 g so we were checking what was the really wrong thing we was checking and checking is like what should we do next, and we did in for the things in the box had to be different because our observation of the two boxes are different, and we observed yes things are different of course.
and there's a picture with the observation chart I will be showing it's above take a look and you will be have more understanding and knowledge about the really topic I am talking about thank you.
Hemoglobin is the oxygen carrying compound found in human blood. It is found to contain 0.3335% iron by mass. It is already known that one molecule of hemoglobin contains four atoms of iron. What is the molecular mass of hemoglobin in g/mol
Answer:
66986.51 g/mol
Explanation:
According to this question, Hemoglobin- an oxygen carrying compound in the blood, is found to contain 0.3335% iron (Fe) by mass.
* One molecule of hemoglobin contains four atoms of iron
If 1 atom of Fe = 55.85g/mol
Then 4 atoms = 4 × 55.85 = 223.4g/mol
So there are 223.4g/mol of Fe in one molecule of hemoglobin
If hemoglobin contains 0.3335% iron by mass, this mathematically means that:
223.4g/mol of Fe ÷ molar mass of hemoglobin = 0.3335%
That is;
223.4/M.M = 0.3335/100
Cross multiply
0.3335 M.M = 22340
M.M = 22340 ÷ 0.3335
M.M = 66986.51
Hence, the molar mass of hemoglobin is 66986.51g/mol.

What process facilitates locomotion for the ovum?
Question 6 options:
a. Once the ovum leaves the ruptured follicle it is captured by the uterus and then directed into the Fallopian tube, where it is pushed along towards the oviducts.
b. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
c. Once the ovum leaves the ruptured follicle it is fully matured and propels itself into the Fallopian tube, where it moves along towards the uterus.
d. Once the ovum leaves the ruptured follicle it is captured by the cervix and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
The correct answer is B. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
Explanation
Ovulation is a process in which the ovum is released from the ruptured follicle, there it is captured by the fimbriae and taken to the fallopian tubes (where it will be fertilized by sperm) and then it will reach the uterus (the place where the fetus will grow) through the cilia. Additionally, this process is in which the woman is fertile to conceive and occurs around the fourteenth day of the menstrual cycle (which lasts twenty-eight days).

Autoclaving is the most effective among all moist heat-related antimicrobial methods. (True or False)
Answer:
True.
Explanation:
Autoclaving is the most effective among all moist heat-related antimicrobial methods because this method can kill all the harmful microbes such as bacteria, fungi and viruses. Moist heat causes destruction of microorganisms by denaturation of macromolecules that is present in their body such as proteins. Autoclaving is a very common method for moist sterilization. It is an effective method in killing fungi, bacteria, spores, and viruses but it does not eliminate prions.
Which is an example of temporal isolation?
flowers that bloom in different months
birds that have different mating calls
fruit flies that mate in different locations
squirrels that have different fur colors
Flowers that bloom in different months is an example of temporal isolaton.
What is temporal isolation?Temporal isolation is a type of reproductive isolation that occurs when two or more species reproduce at different times, thereby preventing mating between them. This can happen in a variety of ways, such as when one species is active during the day and the other at night, or when they breed during different seasons.
Temporal isolation can lead to the evolution of new species because it prevents interbreeding between populations that would otherwise exchange genetic material. Over time, these isolated populations can accumulate genetic differences that make it increasingly difficult for them to interbreed, leading to the formation of distinct species that are reproductively isolated from one another.

What can you tell about an igneous rock that has a coarse-texture?
A. It is a carbonate.
B. It probably formed in a volcanic eruption.
C. It is most likely formed underground.
D. It is extrusive.
Answer: It is most likely formed underground
An igneous rock that has a coarse texture is one that formed from slowly cooling magma deep within the Earth's crust, or from slowly cooling lava on the surface. The slow cooling allows large mineral crystals to grow, giving the rock a coarse, grainy texture.
What can the size and shape determine ?The size and shape of the mineral crystals within the rock can provide information about the rock's cooling history and the conditions under which it formed. Coarse-grained igneous rocks such as granite, gabbro, and diorite typically have crystals that are visible to the open eye, with sizes ranging from a few millimeters to several centimeters in diameter.
The composition of the rock can also be determined based on the types of minerals present in the coarse-grained texture. For example, if the rock contains primarily feldspar and quartz, it is likely a granite. If it contains mainly plagioclase feldspar and pyroxene, it is likely a gabbro.
Overall, the coarse texture of an igneous rock indicates that it cooled slowly over a long period, allowing mineral crystals to grow and form a visible grain structure. The size and composition of the crystals can provide clues about the rock's history and origin.

Answer:
The correct answer is -
variation, over population and adaption.
Explanation:
Natural selection is the process to which the various species and populations are able to adapt and change according the environmental changes. It is affected by three main factors that are variation, over population and adaption.
Variation: varion is one of the factor that pushes the population to change towards the beneficial variation in the population for their survivability and reproducing theirselves.
Overpopulation: over population increases the competition amon population and there fore there resources become limited so few have to change or their ways of utilizing resources.
Adaption: Adapting the change takes place due to any situation in environmental that put stress on the population allow them to adapt according the change or they will extinct.
