Answer:

DNA ligase

Explanation:

After Okazaki fragments (sequences complementary to the lagging strand of DNA) are produced, they must be joined together to produce a continuous strand. The Okazaki fragments are then joined up by DNA ligase, which catalyzes the formation of a phosphodiester bond between the neighboring nucleotides.

Please help!! I WILL GIVE BRAINLIEST !! Can you figure out the modern spreading rate of the Mid- Atlantic ridge? Use that line t

Naddik [55]

Answer:

R = 16mm/y

Explanation:

Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)

R = d/t

To calculate it in millimeters per year we need to convert it:

1 km = 1000 m

1 m = 100 cm

1cm = 10mm

1 km = 1,000,000 mm

The problem states that in 150 million years, there is a distance of 2400 km.

if 1 km ------- 1,000,000 mm

2400 km-------X = 2400,000,000 mm

If 1 million years -------1,000,000 years

150 my----X = 150,000,000 years

R = d/t

R = 2400,000,000 mm/150,000,000 y.

R = 16mm/y

The diagram below shows the stump of a tree whose root grew into a small crack in bedrock and split the rock apart.

Drupady [299]

Answer:

Physical Weathering

Explanation:

As per the given conditions in the question, the primary effect is mechanical action which is also known as a physical weathering. During mechanical action, a rock is disintegrated into the smaller pieces. In the given statement, the root of tree would grow in the crack and try to develop a strong network to get nutrients necessary for tha tree growth. Thus, the root would exert a pressure in the crack to make more space for its growth and development (root network). This is primarily a mechanical action and an example of physical weathering.

Consider the following statement by a project analyst: "I analyzed my project using scenarios for the base case, best case, and

s344n2d4d5 [400]

Answer: It is important to conduct many different experiments and estimates in a project for having as much statistic data as possible, because it is necessary to show proof on whichever project you are into. In order to avoid confusion, it's also possible to organize data in Excel sheets/tables so it can be visually easier to interpretate. Gut instinct isn't enough to prove something wrong or right, and few data means higher probability of things going in ways other than the expected.

In your own words Describe how autotrophs and heterotrophs obtain energy. please this answer must be at least 150 words any one

blsea [12.9K]

The autotrophs are the primary producer in the food chain and they are the ones who initiate the food chain. They produce food by using sunlight or sometimes chemical energy or reactions. They primarily use carbon dioxide, sunlight and water to form sugars or carbohydrates which become their energy source. They use the process of photosynthesis or chemosynthesis to generate food. Examples of autotrophs are green plants, green algae, bacteria.

Heterotrophs cannot make their food via sunlight or other inorganic sources and hence are dependent on the autotrophs or other animals. The heterotrophs have been ranked as secondary and tertiary consumers and cannot be producers. They consume the organic products made by autotrophs to obtain energy for various metabolic and biological activities. The heterotrophs can be herbivore, carnivore, fungi, parasitic plants.

Some are photo-hetrotrophs, who use light as energy but cannot use carbon dioxide as the carbon source since they cannot fix the carbon like autotrophs.
