Answer:

Crashing into the asteroid would cause the satellite to slow down, stop, or reverse direction, because it is a force in the opposite direction to the satellite's motion. Whichever crash was a stronger force would cause it to change motion more. It takes a stronger force to change the velocity of a more massive object.

Explanation:

Big change occur in the motion of the satellite when it is hit by a big and heavy object.

The crash greatly affected the motion of the satellite because the other object comes to the satellite in opposite direction which slower down the speed and sometimes also reverse the motion of the satellite.

That crash will bring great change in the motion of the satellite which is hit by a big and heavy object whereas if the object is small than it only slow down the speed of the satellite so we can conclude that the interaction with greater object will greatly affected the motion of the satellite.

We wrote a scientific statement explaining the changes in plant growth in the Chesapeake Bay since 2014.

Known for its beauty and abundance, the Bay has become "emptier", with fewer crabs, oysters and sailors (fishermen) since the mid-20th century. Nutrient pollution and urban runoff have been identified as major components of impaired water quality in the bay's stress ecosystems and aggravating shellfish decline due to overharvesting.

The bay is facing other environmental concerns, including climate change that is causing sea level rise that erodes coastal areas and infrastructure and changes to the marine ecosystem. These changes have already changed the coastline, eroding islands like Holland Island or Long Island and threatening local infrastructure and economies.

With this information, we can conclude that the environmental changes caused a great change in the biotic factors in the Chesapeake Bay.

Answer:

Fatty acid degradation produces acetyl-CoA

When carbohydrate concentrations drop, any available oxaloacetate is diverted to gluconeogenesis to produce the glucose necessary for red blood cell and brain function. If acetyl-CoA cannot enter the citric acid cycle (and acetyl-CoA cannot be converted to pyruvate in mammals), it is converted to ketone bodies.

The only option that could never be part of the bark is the Secondary Xylem. Here option B is the correct answer.

Cortex: The cortex is the region of tissue located between the epidermis and the vascular tissues (xylem and phloem) in the stem or root of a plant. It is commonly present in the bark, providing structural support and conducting materials. Therefore, the cortex can be part of the bark.

Secondary Xylem: Secondary xylem, also known as wood, is responsible for providing structural support to the tree. It is formed internally to the bark by the vascular cambium. While it is an essential component of the tree trunk, it is not part of the bark itself.

Primary Phloem: Primary phloem is the outermost tissue of the vascular bundle, responsible for transporting sugars and other organic compounds produced by the leaves. It is commonly present in the bark and contributes to its composition. Therefore, the primary phloem can be part of the bark. Therefore option B is the correct answer.

Answer:

A

Explanation:

In some angiosperm plants, pollen grains express spikes on their surface that help them stick to the pollinator's body and incrceases the chances of cross-fertlization. Option B. Angiosperm.

Different families among the Angiosperm group produce pollen with spikes on their surface.

This is a strategy developed by these plants to ensure cross-fertilization. Let us remember that pollen is the masculine cell released by the masculine organ of the plant. This cell meets the ovocell and fertilize.

In cross-fertilization, pollinators play an important role since they carry pollen from one plant to another one.

To ensure pollen sticks to the pollinator's body and succesfully get to another flower, Angiosperm developed spikes that help the grain to  cling to the pollinator's body. Once the insect get to the new flower, pollen is deposited, increasing the chances of cross-fertilization.

The correct answer is b. Angiosperm

Explanation:

Answer: T T A A G C G G C CA TAA T C T G CTT

Explanation: The A's always pair with T's.    The G's always pair with C's.

It is possible for enzymes with G = 0 (near equilibrium) to catalyze both directions of reaction (are reversible). based on P/R in the cell, will catalyze reaction in thermodynamically favorable direction. The direction can be controlled by altering the P/R ratio through differential regulation of the irreversible enzymes in each pathway.

An energy input is necessary for anabolic reactions, which entail the synthesis of larger, more complex molecules from smaller, simpler ones. The chemical bonds in bigger, more complex molecules are broken during catabolic events, which are the opposite of anabolic ones.

Being able to use a Punnett square to track the pattern of inheritance in a two-characteristic cross (such as pea seed color and seed shape) demonstrates Mendel's idea of independent assortment.

Independent assortment is one of Mendel's fundamental principles of inheritance. It states that during the formation of gametes (eggs or sperm), the alleles for different traits segregate independently of each other. In other words, the inheritance of one trait does not influence the inheritance of another trait. Using a Punnett square allows us to predict the possible combinations of alleles and the resulting phenotypes in offspring for a particular cross. In a two-characteristic cross, the Punnett square helps visualize the independent assortment of alleles for each characteristic and their potential combinations in the offspring. By filling in the Punnett square with the alleles from each parent and observing the resulting genotypes and phenotypes of the offspring, we can determine the expected pattern of inheritance for the traits being studied. This analysis supports Mendel's idea of independent assortment, as it demonstrates how different traits are inherited separately, allowing for a wide variety of possible combinations in the offspring

Transmission electron microscopy (TEM) is used to view the internal structures of a specimen. Option A.

It is a type of electron microscopy that uses a focused beam of electrons to form images of the specimen on a fluorescent screen or on a photographic film. In this technique, the electrons pass through a thin section of the specimen, and the resulting image is an image of the internal structure of the specimen.

A transmission electron microscope (TEM) works by passing a beam of electrons through a specimen to create an image of the internal structure of the specimen. A sample must be thin enough to allow electrons to pass through it, and it is typically stained with heavy metals to improve contrast.

The electrons interact with the atoms in the sample, and some electrons are scattered while others pass through to create an image on a screen or detector.
