A genetic cross between two F1-hybrid pea plants for spherical seeds will yield 50% of plants with a heterozygous genotype in the F2 generation. Thus, the correct option for this question is C.
What is a Genotype?A genotype may be defined as the ultimate combination of alleles of those genes that are subsequently selected for specific study in order to reveal some genetic facts and traits of an individual.
According to the question, the two F1-hybrid pea plants for spherical seeds have the genotype of Rr and when these two genotypes are crossed with one another, it produces offspring with the genotypes RR, Rr, Rr, and rr. In this set of offspring, 2 of them have heterozygous genotypes.
Therefore, a genetic cross between two F1-hybrid pea plants for spherical seeds will yield 50% of plants with a heterozygous genotype in the F2 generation. Thus, the correct option for this question is C.

Happy9. Do you think that squid have the same type of body organization that humans do? (i.e. cells form tissues
which form organs which form systems) Why or why not?
Answer:
No
Explanation:
They are mollusks
No, the squid have the same type of body organization that humans do i.e. cells form tissues which form organs which form systems as well as unicellular and multicellular organisms.
What is difference between unicellular and multicellular organisms?The main difference between the unicellular reproduce organisms in other hand multicellular-repairs dead or damaged cells. They both help develop and grow in the multicellular this organism has been made up of 2 or more cell they can be made up to trillion if cells, it is much more complex than the unicellular. They reproduce asexually and the cells cannot live outside the organism, they perform specialized functions an example the nerves.
Cell division in unicellular organisms is important for reproduction. Unicellular cell division used for single-celled organism. Cell division in unicellular organisms is used for the reproduction of an organism.
The importance of cell division in multicellular organisms is the development and replacement of damaged and dead cells. Cell division is important for tissue growth and cell maintenance.
Therefore,No, the squid have the same type of body organization that humans do i.e. cells form tissues which form organs which form systems.

Why do carnivorous plants eat insects?
Answer:
Meat-eating, or carnivorous, plants can trap and digest insects and other small animals. They do this to obtain the vital nitrogen that they need to grow. Most plants absorb enough nitrogen from nitrates in the soil. Carnivorous plants live in bogs, where nitrates are in short supply, so they need to obtain their nitrogen by digesting prey instead. Carnivorous plants have developed unique ways to catch insects, such as fluid-filled PITCHERS and spring-loaded traps.
In what type of rock do paleontologists generally look for fossils?
Answer:
Sedimentary Rock.
Explanation:
Not every type of rock contains fossils so paleontologists focus their discovery on areas with the type of rock most likely to contain them like said sedimentary rock.
- hope you have a nice day :)
Answer: They usually look for Sedimentary rock.
Explanation:
Most fossils "hide out" in sedimentary rock . When tiny bits of rocks and minerals (called sediment) join together over millions of years, they become sedimentary rock. Plants and animals that become sandwiched in this sediment eventually turn into fossils.
Calculate how much DDT you would consume if you ate 3 kg of squid (calamari).
Answer:
66 000 mg or 66g
Explanation:
If a person consumes 3 kg of squid, the amount of DDT consumed cannot be confirmed because the amount and concentration of DDT vary; for example, if the squid is caught in an area where DDT is widely used, the squid contains more DDT.
What effect does DDT have on animals?DDT is commonly used in pest control, but it is eventually replaced by other chemicals due to its numerous environmental side effects, which include the thinning of eggshells in birds, accumulation in the fatty tissues, disruption of the endocrine system of animals, etc., and being highly toxic to animals and birds, etc.
Hence, if a person consumes 3 kg of squid, the amount of DDT consumed cannot be confirmed because the amount and concentration of DDT vary; for example, if the squid is caught in an area where DDT is widely used, the squid contains more DDT.

(2) creation of new employment opportunities
(3) decrease of property values in the area around the plant
(4) increase of automobile traffic in the area around the plant
Answer:
2
Explanation:
they are basically asking what positive factor is the town using to jusify the pollution it will bring
The town officials most likely gave their approval because the negative impacts would be offset by the creation of new employment opportunities. Thus, the correct option for this question is B.
What are the negative impacts on the environment?The negative impacts on the environment as the result of the establishment of a new automobile manufacturing plant are as follows:
It releases a number of pollutants into the environment.It creates a shortage of water and electricity. It affects the well-being of all living entities.Although the establishment of a new automobile manufacturing plant provokes many negative impacts on the town, still it is a trade-off that the town officials gave their approval due to the creation of new employment opportunities in the town.

What is the connection between the rising concentration of SO2 And NO2x , And The Acid Rain Pollution Alert?
Answer:
Acid rain refers to the rain which acidic in nature having a form of precipitation and elevated levels of hydrogen ions (low pH). The normal pH of rain is around 5.6
Rising concentration of Sulfur dioxide (SO2) and nitrogen oxides (NOx) in atmosphere is one of the cause of acid rain. Sulfur dioxide (SO2) and nitrogen oxides (NOx) are released by vehicles, fossil-fuel power plants and oil refineries.
When a sulfur dioxide and nitrogen oxides released in air they mix with oxygen, water and other chemicals in the air and form sulfuric and nitric acids. sulfuric and nitric acids mix with precipitation and its pH level is about 5.2 or below.
Hence, rising concentration of SO2 And NO2x is one of the biggest reason of acid which damages agriculture, buildings and wildlife et-cetra.

State lab review packet answers diffusion through a membrane -beaks of finches - making connections - relationships and bio diversity
Answer:
Diffusion can happen with or without a membrane. It always takes place down a concentration gradient, which means the substance will diffuse from an area of higher concentration to an area of lower concentration.
Biodiversity is critical to maintaining the balance of the ecosystem. Without a diverse collection of organisms, the species in the environment cannot thrive and are at a risk of extinction in extreme cases.

Why do you think naming the lynx might be advantageous for its survival? (please help)
Answer:
Lynx are wild animals, which act as predators in regulating the populations of their prey.
Lynx are dangerous for humans but humans are more dangerous for them because they are hunted for their skin.
Naming the lynx will be advantageous for its survival because it will give them a unique identity and will increase care for them. Naming the animal create a different bond between human and animals which changes the way humans regard animals.
So, naming the lynx might decrease the hunting of lynx and will increase its chnaces to survive.

Answer:
The pocket mouse is generally found in rocky outcrops in the deserts of the southwestern United States and Mexico.
Though the fitness of an organisms helps them to survive and produce offspring but the color of pocket mouse influences its fitness because the color of mouse helps them to survive from the predators. The rock pocket mouse having light color fur blend with dark sand and blend with the sand which increases their chances of survival and the allele for dark fur will be passed on to their offspring.
