New generations are better suited to their environment than the first generation. What is this called?
Answer:
Descent with modification
Explanation:
We define evolution as descent with modification from a common ancestor.
Evolution only occurs when there is a change in gene frequency within a population over time. These genetic differences are hereditary and can be passed on to the next generation - which is what really matters in evolution: long-term change. In this process, the new generations are better suited to their environment than the first generation because of descent with genetic modification.
Final answer:
New generations are better suited to their environment than the first generation due to evolution by natural selection. Individuals with advantageous traits tend to survive, reproduce, and pass these traits to their offspring, leading to better adapted future generations.
Explanation:
The phenomenon where new generations are better suited to their environment than the first generation is known as evolution by natural selection. This process occurs because the members of a population have genetic variability, which results in some individuals having traits that give them a biological advantage in specific environmental conditions. These individuals are more likely to survive and reproduce, passing on these advantageous traits to their offspring. Over time, these traits become more common within the population, making future generations progressively better adapted to their environment.

What causes upwelling?
Explanation:
Upwelling is a oceanographic phenomenon. It is a process which results in the replacement of warm and nutrient less water with the cold and nutrient enriched water at the surface of oceans, seas, etc. As a result of this process, the surface water rises. The phenomenon behind this process is that the high intensity winds move the cold water from the middle of the ocean or sea towards the surface of the ocean or sea replacing the warm water which was present there. Due to this process, the nutrient enriched water reaches the surface of the oceans and seas.

Name any 3 methods of irrigation and briefly describe them.
Nutrients can also be provided through irrigation to the crops. The different sources of water for irrigation are wells, lakes, ponds, canals, tubewells and even dams.
What is irrigation?Irrigation is defined as the process of applying water to the crops artificially to realize their water requirements.
The three important methods of irrigation are sprinkler, surface, and drip/micro.
Water flows over the soil by gravitation force for surface irrigation. Sprinkler irrigation, also known as spray irrigation, is a means of dispensing water in a regulated manner, comparable to rainfall. Pumps, valves, pipes, and sprinklers may be used to disperse the water. Irrigation sprinklers can be used in a variety of settings, including residential, industrial, and agricultural.Drip irrigation entails laying tubing with emitters next to the plants on the ground. The emitters trickle water into the root zone of the soil slowly. Plant production and quality improve as moisture levels are maintained at an appropriate level.For more information regarding irrigation, visit:

Which step of the scientific method relies more heavily on newly collected data than on creativity and innovation?
drawing a conclusion
designing an experiment
solving a problem
formulating a question
Answer:
The best possible answer is: Drawing a conclusion.
Explanation:
in orde to write a conclusion report on an experiment you need the data collected from the experiment. Designing the experiment requires too much trial and error. formulating the question is purely a made up idea until tested. However, solving a problem depends on wether it is after the experiment or during. If it is after than you are most likely using information from the experiment, in this case it could be the right answser. If it is during then the it is about what you can do to fix something that went wrong in the experiment. I hope this helps you!

(pl. ova) the egg cell; a female gamete oogamy 5. the form of production of new individuals by two parents in which the offspring obtains half of its hereditary information from each parent mitosis 6. a small, flagellated male gamete that swims to the egg to fertilize it sperm
Answer:
1. Meiosis: The process involving the division of the nucleus in a reproductive cell...
2. Mitosis: the process involving the division of the nucleus of a body cell
3. Oogamy: the condition of having oogametes...
4. Ovum: the egg cell...
5. Sexual Reproduction: the form of production of new individuals by two parents....
6. Sperm: a small flagellated male gamete...
Explanation:
1. Meiosis is a type of cell division that produces gametes, or reproductive cells. The process produces haploids, which have half the number of chromosomes as the parent. Genetic recombination occurs in meiosis, where there is an exchange of genetic information between the chromosomes, which bring about genetic diversity.
2. Mitosis is also a type of cell division, but unlike in meiosis, they produce clones of the parent cell. They produce diploids and this occurs in body cells. The purpose of mitosis is for growth, repair and asexual reproduction.
3. Oogamy is a form of sexual reproduction. What you would observe with oogamy is that one sex cell or "gamete" is bigger than the other gamete and the bigger gamete is non-motile or it can't move, while the other can. The egg cell for example is larger than the sperm cell, but it cannot move, while the sperm cell can.
4. The female gamete is called the ovum, plural form would be ova. This is also known as the egg cell. It is non-motile, so that means it cannot move. It's main purpose is to be fertilized by the sperm cell.
5. Sexual reproduction is the fusion of two gametes, which produces a fertilized egg, or a zygote. These gametes are haploid cells, which are produced in meiosis, and they each have half the genetic information of their parent cell. Thus the offspring produced will be genetically different from their parents.
6. The sperm cell is the male gamete. It has a flagella, which is like a tail that helps it move. It's main purpose is to fertilize an egg cell.

What might geneticists learn about genes by studying rna.
by studying RNA, geneticists could learn about where genes begin and end on a chromosome. they could also learn about where genes are active in different types of the cells.
By studying RNA, geneticists can learn about gene expression patterns, how changes in RNA can affect these patterns, and gain insights into the complex genetic code that defines each protein sequence. RNA's roles in transcribing DNA and translating it into proteins are also significant areas of understanding.
Explanation:Geneticists can gain a wealth of knowledge about genes by studying RNA, particularly regarding gene expression. RNA stands for ribonucleic acid, a molecule that plays a crucial role in the process of transcribing the genetic instructions inscribed on DNA and translating them into proteins. Each protein sequence is determined by a three-nucleotide sequence in RNA called the triplet codon, effectively forming a genetic code.
By studying RNA, geneticists can discern patterns in gene expression and even predict how changes in specific DNA or RNA sequences could potentially alter this expression. For instance, the Human Immunodeficiency Virus (HIV) is an RNA virus that uses its RNA as a template to create DNA, demonstrating a deviation from the standard genetic flow of information. This highlights the importance of RNA in the realm of genetics and why its study is so vital to understanding the complex interplay of genetic expressions in living organisms.

A. The part of an aquifer where groundwater meets a lake or stream
B. The part of an aquifer where surface water reaches the water table
C. The part of an aquifer that's located between two aquicludes
D. The part of an aquifer that's located at a lower elevation
Answer:
B. The part of an aquifer where surface water reaches the water table
Explanation:
The recharge area of an aquifer, is the area where the aquifer comes in touch with the surface water. At this area, the aquifer is receiving new and fresh water reserves from the surface, thus replenishing the water that it has lost. Most of this water comes from the rainfall and runoff, though rivers and streams can also contribute to it. The recharging of the aquifer is crucial for its existence, as it constantly loses water, and the recharging in giving back water to it, thus balancing the lost and gained water in it.

The amine group in cysteine is NH₂ found on the left side of the molecule. The carboxylic acid group is COOH found on the right side of the molecule. The R group or side chain in cysteine is CH₂-SH.
Explanation:The amine group in an amino acid is the part of the molecule that contains nitrogen (NH₂). In the case of cysteine, this would be on the left side of the molecule. You can circle this part. The carboxylic acid group is the part of the molecule that contains a carbon atom double-bonded to an oxygen atom and also bonded to a hydroxyl group (C-OH). In cysteine, this would be towards the right side of the central carbon. You can put a box around this. The R group, or side chain, is different for each different amino acid. For cysteine, this is composed of a carbon atom bonded to a sulfhydryl group (CH₂-SH). You can use a different color to circle this part.

Answer:
El Niño would lead to the death of organisms or populations. El Niño would cause organisms to move in search of food and better conditions.Explanation:
El Niño is a climatic phenomenon that has many effects on nature. Basically, this phenomenon is characterized by the promotion of trade bliss from the east towards the west. When this occurs, the result is an accumulation of hot water in the upper layer of the Pacific oceans. With the increase in water temperature, evaporation becomes much higher than normal, forming large clouds laden with water vapor in this region, which will result in a strong rainy season.

Halogens are destructive to ozone because they are highly reactive with oxygen. Please select the best answer from the choices provided T F
Answer:
True
Explanation:
Halogens belongs to the seventh group on the periodic table. This group contains the most reactive set of elements that we have. They require just an electron to achieve a noble and stable electronic configuration.
When halogens mostly in form of ChloroFluoroCarbons(CFCs) reaches the atmoshpere, ultraviolet rays release chlorine atoms which easily breaks away an oxygen atom from ozone. Ozone thereby turns into an oxygen gas with two oxygen atoms instead of three. This reaction depletes the ozone layer.

A scientific law describes a generalized pattern in nature and is often expressed as a mathematical equation, while a scientific theory provides a comprehensive explanation for a group of related phenomena. Scientific laws describe what happens, and theories explain why and how it happens.
Explanation:The difference between a scientific law and a scientific theory is a fundamental aspect of scientific knowledge. A scientific law uses concise language to describe a generalized pattern in nature that is supported by scientific evidence and repeated experiments, often expressed in the form of a mathematical equation. In contrast, a scientific theory is a well-supported explanation of observations; it is more complex and dynamic, explaining a group of related phenomena rather than describing a single action. For instance, Newton's second law of motion, which can be summarized by the equation F = ma, is an example of a scientific law, while the Theory of Evolution is an example of a scientific theory.
Therefore, option C, stating that a theory is why something happens and a law is how something happens, accurately reflects the difference between a scientific law and a scientific theory. Scientific laws describe what happens under certain conditions in nature, often mathematically, while theories provide the explanation behind these observations, elaborating on why and how the phenomena occur.
