How does the decrease in biodiversity impact an ecosystem?
Answer:
because the more alike species are The more they have to adapt to try and compete with one another So the more different a species is the less they have to compete
Answer:
the decrease in biodiversity may cause a significant reduction in the productivity of the ecosystem. The loss of biodiversity means genetic variations are lost and the overall genetic pool reduces.

The following is the results of a genotype being "foiled" for a dihybrid cross: BS | Bs | bS | bs
Determine the parents genotype
A) BBSS
B) BBss
C) BbSs
D) BbSS
Answer:
C. BbSs
Explanation:
The foiled results of the genotype include both capital and lowercase versions of both letters, b and s.
This means the genotype has to be heterozygous for both the B and S traits, since the foiled results have both dominant and recessive alleles.
So, the genotype must be C, BbSs
The foiled results of the genotype for the offsprings include BS | Bs | bS | bs.
The parent's genotype will then be BbSs.
The genotype of both parents have to be heterozygous as a result of the
presence of its forms in the B and S traits. There is the presence of the
dominant (B,S) and recessive traits (bs).
The genotypes of the parent will however have both traits in them which
translates to the option C) BbSs being the most appropriate.

Mendel studied seven traits in pea plants. One of the monohybrid crosses he made was between plants with round seeds and plants with wrinkled seeds.
What was a conclusion Mendel drew from the F1 generation of this cross?
Explanation:
Traits are inherited in discrete units, and are not the results of "blending." ... traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1.
Answer:
The dominant factor, or allele, is for round seeds.
Explanation:
The factors (or alleles) don't disappear when two species are crossed, so "the factors or alleles for round seeds disappear completely from the plants" and "the factors or alleles for wrinkled seeds disappear completely from the plants" are both incorrect. From the drawing, we can see that the F1 generation is a round seed, meaning the dominant factor is for round seeds. Hope this helps!
What are five similarities and five differences between sharks and bony fishes?
[tex]\Huge\text{Pisces or Fishes}[/tex]
Pisces or Class Fish is the largest group of chordates which includes 25000 species of fishes. Study of fishes is called Ichthyology.
Fish is an aquatic gill breathing gnathostomates whose stramlined body is provided with paired fins and covered over dermal scales.
Super Class pisces is divided into two classes:
Chondrichthyes Osteichthyes _____________________________________
[tex]\Huge\textbf{Chondrichthyes}[/tex]
Chondrichthyes are Cartilagineous fishes. This class is also called Elasmobronchi. It has exclusively marine fishes with endoskeleton made of cartilage. Their skin has tiny shark enamel coated denticles called Placoid Scales. They are heterocercal and Mouth is present at ventral to tail fins. They have exposed 5 gills on each sides.
Example Shark, Ray fishes, Dog dish etc
_____________________________________[tex]\Huge\textbf{Osteichthyes}[/tex]
These fishes are Bony Fishes. This group is also called Teleostomi, They are found in both marine and fresh water. Their endoskeleton is made up of bones. Their skin has thin bony plates called cycloid or ctenoid. Their gills are covered with outer skin called operculum. Tain fin is homocercal and mouth is present at anterior tip.
Examples Sea Horse, Gold fish, Eel etc
_____________________________________[tex]\huge\text{Similarities}[/tex]They have gill to breath Streamlined body to move in fast moving water All fishes are cold-blooded.

Chondrichthyes are exclusively marine fishes while Osteichthyes are both fresh water and marine water living.The skeleton of Chondrichthyes is made of cartilage while the skeleton of Osteichthyes is made of bones.The gills of Chondrichthyes is NOT covered with operculum while the gills of Osteichthyes are covered with outer skin operculum. The skin of Chondrichthyes has tiny shark enamel coated denticles called Placoid Scales while the skin of Osteichthyes has thin bony plates called cycloid or ctenoid.The tail of Chondrichthyes is Heterocercal and mouth is ventral to the tail fins while the tail of Osteichthyes is homocercal and the mouth is present at anterior tip._____________________________________Best Regards,'Borz'A certain species of trilobite is known to have lived 300 million years ago. If this index fossil was found in a rock layer containing other fossils, what could you infer about the other fossils
a The rock layer killed the trilobite and the other fossils
b The other fossils are about 300 million years old
c The organisms that formed the other fossils are still living.
d The rock layer formed before the trilobite and other organisms
Answer:
b The other fossils are about 300 million years old
Explanation:
From the description of the problem given, we can correctly conclude that the other fossils are about 300 million years old and even the rock layers formed around that period in time too.
Fossils are the preserved remains of organisms that has once lived. Through the principle of relative dating we can determine the age of fossils and those of other related ones. According to the principle of fossil and fauna succession, "fossils succeed one another in a predetermined form". So, the fossils occurring together within the rock layers are of the same age.help plzzzzzzzzzzzzzzzzzzzzzz

Tropical rain forests receive heavy rainfall. How do the trees and plants of this region withstand rotting?
Answer:
The trees and plant withstand rotting in tropical rain forest using some of these mechanisms.
Explanation:
Tropical rain forests are known for the presence of heavy rainfall, due to this, there might be a lot of water retention in the root. Some trees and plants however are able to store this water and use some of the below mentioned methods to prevent decay and rot.
Some trees in the tropical rain forest may produce very hard outer layer, these hard outer layer will protect the plant and trees form predators and microorganisms from penetrating into the inner tissues of the tree.
Some withstand rotting by producing chemical compounds, these chemical compounds prevents predators and microorganisms from destroying the plants and trees.
How do animal behaviors lead to successful reproduction and growth of their young?

1 Invasive plant species affect the interactions of living and nonliving components
of an ecosystem, so the removal of invasive plants is often necessary. The goal of
most plant-control methods is to disrupt or inhibit the function of different plant
systems. For example, insects can be used to chew through roots in order to
reduce a plant's ability to absorb water.
Which of these functions would be most immediately affected by a reduction in water
uptake by roots?
A Disease resistance
B Seed dispersal
C Sunlight absorption
D Photosynthesis

What provides evidence of an increase in animal species at the same time that atmospheric oxygen concentrations increased?
ts fossil records but i need an explination
Answer:
Fossil records provide evidence of an increase in animal species at the same time that atmospheric oxygen levels increased.
Explanation:
A huge diversification among animal species occurred with the increase in the levels of atmospheric oxygen. The reason why the number of species increased drastically was that a whole new world opened up, the land. The land was open for exploitation and taking over, with every single niche free, so animals diversified and filled in pretty much all of the niches. The fossil records give us clues when this happened, as from only microorganisms there is a sharp rise in complex animals, coinciding with the increase of oxygen levels.
If it wasn't for the increase of atmospheric oxygen though this wouldn't have been possible. The oxygen in the atmosphere enabled animals to breathe on land. Also, it cooled off the global temperatures which were too high before the increase of atmospheric oxygen, making them suitable for life. And last but not least, the atmospheric oxygen resulted in the formation of the ozone layer, a layer that started to act as protection from the UV rays.
Answer:fossil record
