not everyone has radial symmetry
Can someone answer this please.
Answer:
Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.The first true primates evolved by 55 million years ago or a bit earlier, near the beginning of the Eocene Epoch. Their fossils have been found in North America, Europe, and Asia. They looked different from the primates today.

Wich action would most likely increase the amount of carbon in the environment
Answer:
Cutting down trees
Explanation:
Of course this is just my opinion, but stopping the production of oxygen can greatly effect the carbon and oxygen ratio thus, increasing the level of carbon in the air. There are many different ways for the increase of carbon to take place but I think that cutting down trees has a major effect.
This type of reproduction in plants is centered around the flower's ovum
and pollen fusing together:
Answer:
sexual reproduction
Explanation:
The type of reproduction in which the ovum and the pollen of a flower fuse together is refer to as sexual reproduction.
The ovum of a flower is equivalent to the female reproductive part while the pollen is equivalent to the male's reproductive part. During fertilization, the female reproductive part (the ovum) fuses with the male's reproductive part (the pollen) to produce a zygote.
Why does sexual reproduction result in more genetic variation. In a species than asexual reproduction
Explanation:
Asexual has to rely to its own gene pool and makes a "clone" of itself since Asexual requires one being while Sexual reproduction is two beings and has two gene pools to gather genes from = more genetic variation
Answer:
In sexual reproduction, the offspring will not be identical to either parent.
Explanation:
Therefore more genetic variation. This is correct on ape-x, just wanted to let you guys who don't understand know. This is 1.5.2 (cst) correct as of late May 2021. Just here to help. :)
what is the most abundant organism in a food chain
The given question is incomplete as there is no food chain given in the question, but based on the knowledge it can be said so that producers are present in abundant amount in every food chain.
Answer: Producers
Explanation:
The producers can be defined as the organism which have the ability to make food. This food is used by the other organism of the food chain as a soul source of energy.
They are huge in number so that they can produce enough food to meet the requirement of other organisms. Though all of the organisms are not directly dependent on producers ,some of them(carnivores) are also dependent on the organism eating plants(herbivores).
Producers→ primary consumers(herbivores)→ secondary consumers(carnivores)→tertiary consumers(carnivores).
Here, we can see that the all the organism are directly or indirectly dependent on the producers and they are abundant in every food chain.
Ramer wants to find out how pressure affects the force of gravity acting on dust particles in a cloud. Ramer designs an experiment in which he places dust particles in a pressure chamber. He is able to adjust the pressure in the chamber from 0 Pascals to 780 Pascals. What should Ramer use as his control group?
Answer:
A vaccum should be used for the control group chamber.
Explanation:
In an experiment, a control is an experiment or observation designed to minimize the effects of variables other than the independent variable. The introduction of a control increases the reliability of the results; often through a comparison between the control measurements and the other measurements.
A vaccum according to this experiment is a chamber that will have no pressure within it. This will give a benchmark of the effect of pressure in this experiment.

Answer: Water consumption rises because suburban communities use more water.
Explanation:
Urban sprawl can be described as a wide growth of the urban areas without proper planning. When such a large population starts to live in an urban area then the water consumption would be more. Even the construction process to support the urban sprawl will require adequate amounts of water. Hence, option C is correct.
Other options like option D id false because the usage of more water will lead to an increase in water consumption. The water consumption will not drop.

Up to this point, did you notice any differences between the development of male and
female gametes?
Explain
Both male and female gametes are produced by different organs and in different sizes.
The main difference between male and female gametes is that male gametes which are known as sperm cells are produced in large numbers by the male reproductive organs whereas female gametes are called egg cells which are produced single at a time by the female reproductive organs.
Both male and female gametes are formed by meiosis type cell division. The female gamete is a large in size and motile while the male gamete is small in size and also motile so we can conclude that both gametes are produced by different organs, numbers and sizes.

Microplastics are currently in our ocean's food web.
True
False
Answer:
True.
Explanation:
However, it has been established that microplastics enter the food chain when animals eat or ingest contaminated food materials. ... Zooplankton, the microscopic sea organisms at the bottom of the food chain, is eaten by all kinds of fish. Fish ingest small pieces of plastic due to their continuous uptake of water.
Answer:
True
Microplastics are one of the most pervasive global pollutants, and their presence in our oceans is a cause for great concern. As the name says, these are micro particles, less than 5mm in size, that have either been deliberately manufactured (e.g., microbeads in cosmetics), or emerge as larger plastics break down (nets, bottles, bags, clothing, etc.). They are roughly the same size range as plankton, and so when they show up in marine ecosystems they have the potential to be consumed by a vast array of organisms.

1. In Japanese four o'clock flowers, color is inherited by genes that show incomplete dominance. In such flowers, a cross between a homozygous red flower and a homozygous white flower will always result in pink flowers.
Answer:
Explanation:
Incomplete dominance occur when two allele expresses itself in the phenotype of an organism.
Its a situation where by an allele is not dominant over another other in an heterozygous condition but it gives a blend of the two allele in the phenotype of the offspring.
Example is the phenotype of a 4'o clock plant that gives pink flower when a red flower is crossed with white flower.

How does the urban and natural water cycle compare?
Answer:
Explanation:
he natural water cycle is a continuing process of evaporation, condensation, precipitation and groundwater (Figure 1). ... The urban water cycle (Figure 2) shows the consequences of increased development. More development and more concrete means less infiltration of rainwater into the soil, and more run off.
~Hope it helps! And stay safe~
Both the urban and natural water cycles have a lot of differences in their properties and occurrence. This is because due to the presence of artificial surroundings in urban areas.
What do you mean by the water cycle?The water cycle may be defined as the continuous movement of water throughout the atmosphere. It involves all the processes and stages of water.
Due to the development in the urban areas, the natural water cycle gets affected. The natural water cycle deals with evaporation, condensation, sublimation, etc. but the urban water cycle has concrete walls, infertile soil, and a ruptured environment where there is less or no rainfall at all.
Therefore, Both the urban and natural water cycles have a lot of differences in their properties and occurrence.

Sometimes scientist disagree. For example, the models about how the oceans formed can be looked at as inside-out or outside-in. How does this type of disagreement fit into the scientific process?
By evaluating opposing arguments, scientific claims can be examined and strengthened.
Scientific logic depends on conflicting data collected by different groups.
Logical conclusions can only be made when all parties agree.
Scientific hypotheses are disproved when two scientists come to different conclusions.
Answer:
By evaluating opposing arguments, scientific claims can be examined and strengthened.
Explanation:
The purpose of argument is to establish a better, more accurate conclusion. This is demonstrated in the given scenario: because there is disagreement, scientists work hard to find conclusive evidence towards one point or another.
Why not B: It doesn't really depend on conflicting data, though a bigger sample size and more groups helps to get a wider representation. You want your results to gradually converge.
Why not C: This is so untrue! Disagreement is key to healthy discussion and honing down scientific points.
Why not D: Two scientists can disagree; this doesn't flat-out disprove hypotheses. What it does is cast light on their discrepancy and lead them to improve their conclusions or do more research.

Health care professionals are seeing increased instances of bacterial infections that do not respond to standard treatments. The infections are caused by bacterial "superbugs" that cannot be killed by standard means. Which of the following has led to this development?
a. Overuse of antibiotics
b. Underuse of vaccines
c. ineffective use of disinfectants
d. inadequate hygiene practices
Answer:
A
Explanation:
Bacteria are treated using antibiotics. Antibiotics disrupts their ability to reproduce, allowing the body's immune system to eradicate the bacteria quickly.
However, if antibiotic treatment is not completed fully, some bacteria may survive the antibiotic treatment and develop immunity due to certain bacteria accumulating enough mutations or undergoing homologous recombination of antibiotic resistant genes from other bacteria strains, causing resultant bacteria to be resistant to that particular type of antibiotic. As time progresses and the types of antibiotic used differs in strength and type, the cycle repeats and the final resultant strain of bacteria is one that is considered a superbug whereby antibiotics are no longer efficient to help the body eradicate the bacteria.
Answer:
a. Overuse of antibiotics
Explanation:
What is the mass number of an ion with 106 electrons, 157 neutrons, and a +1 charge?
The answer is NOT 126
The ion has 106 electrons and 157 neutrons and +1 charge.
This means the original atom has lost one electron originally there are 107 electrons in the neutral atom which shows that there are also 107 protons. 264 is the mass number.
electrons=protons = 107
Mass number: 107 + 157 = 264 g/mol
What are the components of an atom ?The atomic structure consist of three particles proton, neutron and electron.
Protons are the positively charged particles present in the nucleus of the atom.
The charge of a proton is equal to the charge of an electron to maintain the balance in the atom.

What small changes could we make in our everyday routines that could greatly impact our future and the future of species and biomes?
Answer:
Explanation:
Learning to take care of our environment is one great change that we need to make. Our environment is everything around us if we accept the task of taking care of it many species will be preserved for long. If I have river around me and I avoid polluting it to prevent accumulation of toxins in the water bodies this will help the biomes.
When trees are preserved and not been cut down indiscriminately reducing global warming in the environment this will also help preserve biomes.
Answer and Explanation:
There are many small changes that we can make in our everyday routines, and that will have a positive impact on future generations as well as on species and ecosystems.
To name a few,
Transport: we can avoid using cars or motorbikes that need fuels, and we can try to move by bike or walking to other places that are not too far away from where we are. Fuel pollution is very harmful to the atmosphere because of the gasses production. Recycling: whenever it is possible we might try to transform things we do not use anymore in other things. In this way, we will avoid throwing objects that we can reuse.Composting: Every organic waste can be thrown in a pod or space with soil. Organisms will degrade this organic matter and will produce fertile soil.
