At Weeks Bay there was a population of 200 alligators. In May of 2006 a new species of catfish was released into the Mississippi. These catfish reproduce very fast and soon become a rich food source for the alligator population. This provides the alligators with the energy needed for more successful reproduction. The following summer of 2007, 100 babies were born and a total of 40 gators died that year. However, the next year in early 2008 there was a terrible drought, causing 100 alligators to die.

2. What is the growth rate (r) of the alligator population during 2007?

The rocket will then be at least 19.5 m above the ground for the interval 0.75≤t≤3.25  

0.75≤t≤3.25

The time interval for which the rocket is more than 3200 km above the ground level is 61.25 seconds.

To solve this problem, we need to find the time interval for which the rocket's distance above the ground level is greater than 3200 km.

We can start by setting the equation for the rocket's distance above the ground level equal to 3200:

We can then solve this equation for t using the quadratic formula

[tex]480t - 16t^2 = 3200\\t = (-480 +/- sqrt(480^2 - 4*(-16)*3200)) / (-32)\\This simplifies to:\\t = (-480 +/- sqrt(480^2 + 256000)) /\\ (-32)t = (-480 +/- sqrt(2304000)) /\\ (-32)t = (-480 +/- 1500) / (-32)t = (-1980) /\\(-32)t = 61.25t = -24.25\pi[/tex]

Since the time interval we are looking for is positive, we can ignore the negative solution. The time interval for which the rocket is more than 3200 km above the ground level is therefore 61.25 seconds.

Answer:

In a cell, proteins can act as enzymes, structural features, pigments, and a host of other functions, including regulating the expression of other genes. This expression of genes leads to how an organism looks – its phenotype.

Explanation:

Gene regulation creates different types of proteins which make the structure of cell and organism looks, so the gene is responsible for looks and acts.

Gene regulation is a critical component of proper development. During development, genes are switched on and off in diverse patterns to make a brain cell appear and perform differently from a liver cell or a muscle cell, for example.

Gene control also enables cells to respond swiftly to environmental changes. Genetic differences can result from gene variants (also known as mutations) or through a natural process.

Genetic information is reorganized when a cell prepares to divide (known as genetic recombination). Different features in an organism can be introduced via genetic differences that modify gene activity or protein function.

Therefore gene is responsible for how an organism looks and act, it creates different proteins to make a cell.

C. stigma

Explanation:

"stigma"

Fertilization in flowering plants happens through a process called pollination. Pollination occurs when pollen grains from the anther land on a stigma. After pollen grains land on the stigma, a pollen tube grows from the pollen grain, through the style, and into the ovary.

Question:

Use the following dichotomous key to identify an irregular blue flower with five petals and a fruit that is a ripened flower ovary or follicle.

Dichotomous Key of Ranunculaceae

#1.

a. Fruit is a group of alkenes.............................. go to step 2

b. Fruit is a group of follicles..............................go to step 4

#2.

a. Petals are not present.....................................go to step 3

b. Petals are present............................................Ranunculus

#3.

a. The flower has 4 sepals.................................. Clematis

b. The flower has 5 sepals................................... Anemone

#4.

a. The flowers are regular..................................... Aquilegia

b. The flowers are irregular................................... Delphinium

The flower is a: A. Anemone B. Clematis C. Delphinium D. Ranunculus

Answer:

The species belongs to Delphinium genera.

Explanation:

A dichotomous key is relatively simple to interpret. All you need to do is to:

- carefully observe your organism,

- know some technical terms or have a biological dictionary, and

- follow the descriptions.

The dichotomous key is going to lead you to the answer.

In the example, we have a plant species with irregular blue flowers and five petals. The fruits are a ripened flower ovary or follicles.

So, let us begin, step by step. For each number, we are going to have two options (a and b). By knowing our organism, we need to decide which one is correct and follow indications.

#1.

a. Fruit is a group of alkenes.............................. go to step 2.

b. Fruit is a group of follicles..............................go to step 4.

We know that our fruit is a follicle. Option a is not correct (it is not a group of alkenes). Option b is the correct one. Knowing this, we must go to step four. ***Note: In the hypothetical case that the fruits were a group of alkenes, and option a was correct, we should go to step two, as indicated***.

#4.

a. The flowers are regular..................................... Aquilegia

b. The flowers are irregular................................... Delphinium  

We know that our flower is an irregular one. So the correct option is b. This option leads us to Delphinium genera. Our species belongs to this taxonomic group. ***Note: In the hypothetical case that the fruit was actually a regular flower, and option a was correct, our species would belong to Aquilegia genera***

Answer:

ocean gyre

Explanation:

The ocean gyre may be defined as the large system of a circulating ocean currents that is formed as a result of wind patterns globally and by the forces created by the rotation of the Earth. It helps to create a large ocean conveyor belt that helps in circulating the ocean waters in the entire planets. Thus the ocean water keeps a check on the heat of the earth and maintains a balance of heat on the planet.

The ocean gyres makes the movement of the ocean water on the entire globe and thus forms a large loop of the circulating ocean water.

Answer: Red

Explanation:

Sorry if I'm wrong

Answer:

a

Explanation:

Determining the genomes of each species to see which is similar will provide the best evidence regarding the evolutionary relationship of these species. So the correct option is B.

The relationships of different species with each other based on their history of evolution are called evolutionary relationships.

The study of the relationships between organisms by categorizing them into various kinds of groups is called systematics.

All the species of organisms, from bacteria to mammals have evolved from some kind of ancestral species by the process of evolution.

Determination of these evolutionary relationships is the key to understanding the process of evolution. Evolutionary relationships are determined by using evolutionary trees which are diagrammatic representations of ancestral species and their descendants.

The study of genomics to identify the similarity between organisms is yet another useful tool to determine the relationship between them.

Therefore the correct option is B.
