What is an Non-native or Invasive species do to the environment?
Answer:
They can destroy the ecosystem or out - compete a native species.
Explanation:
For example, if an invasive species of tree is taller than the native species of tree and therefore takes up more sunlight, leaving the shorter native tree not enough sun, then it will effectively kill the native tree.
Also non - native and invasive are not the same thing. A non - native species doesn't necessarily mean it's invasive. It is only invasive if it begins to have a significant impact on the ecosystem it is inhabiting.

The variations in the lemming population illustrate
A. the impact that population cycles have on predators
B. the ways in which a lack of food drives species to extinction
C. the benefits that generalist predators have over specific predators
D. how land animals have different population cycles than marine creatures
Answer: A) The impact that population cycles have on predators.
Explanation:
When a prey species is rare, food and space are plentiful, and its population increases rapidly. Meanwhile, the population of predators that feeds on it grows only once the prey population is big enough to fuel expansion
The variations in the lemming population illustrate the "impact that population cycles have on predators".
What is lemming populations change?lemming population cycles are driven by the predatory attentions of the least weasel (Mustela nivalis), which in turn shows a 'predator'-type cycle. Although lots of lemmings fall prey to owls, arctic foxes and suchlike, this isn't what makes their numbers oscillate.
What is population cycles ?A population cycle would be a generally periodic change in such a population's size or makeup over time. The population's component structure, such as its division into different age groups, is referred to as composition in this context.
Hence , A is correct option

1. Name the two processes that occur in meiosis that increase genetic variation
The two factors are: crossing-over and independent assortment. Crossing over: In Prophase I of Meiosis I, homologous chromosomes line up their chromatids and “cross-over”, or exchange corresponding segments of DNA with each other. This produces genetic variation by allowing more combinations of genes to be produced.

Joe When scientists analyze the fossil record, they find organisms that are similar to some organisms of today with noticeable changes. How does this help scientists to
interpret the past?
O A. It doesn't help them at all
B. It allows them to see how organisms have changed over time.
OC. It allows them to see how organisms have remained the same over time.
OD. It allows them to see that there is no relationship between the past and today.
Answer:
B
Explanation:
This allows them to see how organisms have changed over time by comparing fossils to current organisms, which can help scientists understand the organism more and why they lost or gained traits over time

Students model codominance in fish. B is the allele for blue coloring, and R is the allele for red coloring. They draw three fish with different-colored scales and fins. Their drawings are shown in the table.
Select the boxes to show the genotypes for each fish shown.
The phenotype of the fish when both R and Bl are present will be Blue and Red while the genotype will be BR.
What is co-dominance?Co-dominance in genetics is the condition in which alleles of a gene are both dominant in that when both are present in an organism, the organism will show the phenotype of both alleles.
Since the alleles B for blue coloring, and R for red coloring are both dominant, when both are present in the fish, the phenotypic coloring in the fish will be blue and red.

Which of the following is NOT one of the periods of the
Mesozoic Era?
a Cretaceous
b Triassic
C Jurassic
d Paleozoic
Answer:
D.
Explanation:
Paleozoic is not one of the 3 major periods of the Mesozoic Era
Hope that helps!
From 252 to 201 million years ago was the Triassic Period. Between 201 and 145 million years ago is the Jurassic Period. Between 145 and 66 million years ago was the Cretaceous Period, hence option D is correct.
What is the Mesozoic Era?54 million years of the Mesozoic Era, or 199.6 to 145.5 million years ago, are referred to as the Jurassic Period.
The Jurassic Period, so named after the Jura Mountains in France and Switzerland, where rocks from this era were first investigated, has gained widespread recognition.
The Cretaceous is the final part of the Mesozoic Era, lasting from 145.5 million years ago to 65.5 million years ago, and is characterized by the demise of the dinosaurs (except birds).
Therefore, the Paleozoic is not a period of the Mesozoic Era, hence option D is correct.

Question 10 (2 points) Convert a volume of 3.12 x 107 nm into cm3
The conversion of the volume 3.12 × 10⁷ cubic nanometre to cubic centimetre is 3.12 ₓ 10⁻¹⁴ cubic centimetre
How to convert cubic nanometre to cubic centimetre?
The volume is in cubic nanometre, so we have to convert the volume to cubic centimetre.
1 cubic nanometre = 1 × 10⁻²¹ cubic centimetre
3.12 × 10⁷ cubic nanometre = ?
cross multiply
volume in cubic centimetre = 1 × 10⁻²¹ × 3.12 × 10⁷
