Energy from food must be transformed into the bonds of _________ before it can be used by cells.
a.atp
b.gnc
c.nadp eliminate
d.cellulose
Diploid cells have homologous chromosomes. true or false
By conserving energy and making energy transformations more efficient, fossil fuel use could be decreased. True or false
True
Fossil fuels like coal and petroleum takes millions of years to form. The rate of usage of fossils is not equal to its formation. As the rate of formation is slow it is important to use energy in an efficient way so that it is not consumed in a wrong way. The transformation of energy should be more efficient to avoid the wastage of energy. By doing this we can decrease the consumption of fossil fuels as it cause pollution in the environment. The burning of fossil fuel releases carbon dioxide, nitrogen oxide ,and other harmful gases which is injurious to the health of people. So, the fossil fuel should be used in a decreased manner.
______ is a pesticide that influenced society by increasing crop yield, but it also caused human and animal sickness
Dichlorodiphenyltrichloroethane or DDT is a pesticide and insecticide, which was very useful for the yielding of the crops. The DDT exceptionally increased the crop yield, but this pesticide was very harmful for the human and the animal health.
The DDT was well known for causing decreased fertility and reproduction in birds by causing death of the embryo due to thin egg shells. The DDT was very harmful to the aquatic animals. DDT is a carcinogen to humans, and a well known factor for the induction of breast cancer as well as leukemia, lymphoma, and pancreatic cancer.
Hence, the given blank can be filled with DDT.

what goes wrong during the cell cycle in cancer cells?
Gene mutations cause cancer by speeding cell division or blocking normal system mechanisms like cell cycle arrest or programmed cell death.
What are cancer cells?Cancer is a disease that is caused when cells divide in an uncontrolled manner and spread into the tissues that are in close proximity to them. DNA can become damaged, which can lead to cancer. The majority of mutations that can lead to cancer occur in specific regions of DNA known as genes. Alterations of this kind are also referred to as genetic alterations.
There is an imbalance in the number of chromosomes present in many cancer cells; as a result, there may be an excessive number of chromosomes or an inadequate number. The term "aneuploid" refers to the state of these cells. During the process of replicating DNA, mistakes can happen, which can lead to mutations and even the potential development of cancer.

Why do meteorites that hit earth provide evidence of the composition of earths interior?
Meteorites provide evidence of the composition of Earth's interior through their composition, martian origin, and the presence of organic molecules.
Explanation:Meteorites that hit Earth provide evidence of the composition of Earth's interior for several reasons. First, many meteorites are primitive stones that are similar in composition to the outer layer of the Earth's crust. They contain silicates and metallic grains, which are also present in Earth's interior. Second, the analysis of gas bubbles trapped inside some meteorites has confirmed their martian origin. These bubbles match the atmospheric properties of Mars, providing insights into the composition of both planets. Lastly, the presence of complex organic molecules and amino acids in meteorites suggests that they could have delivered the molecular building blocks of life to Earth.

d.) A more biodiverse ecosystem is subject to fewer natural disasters
Answer: Option B
Explanation:
A biodiversity can be defined interaction between the biotic and abiotic components on earth which helps in the serving the human beings with resources.
The more diverse the biodiversity is more stable it will be. A diverse biodiversity will be adapt more easily to the changes.
Plants make their own food. The chemical reaction for this process is shown in the equation below. CO2 + H2O + energy C6H12O6 + O2
What are the products in this chemical reaction?
A. C6H12O6 + energy
B. C6H12O6 + O2
C. CO2 + H2O
D. H2O + energy
Answer:
B. C6H12O6 + O2
Explanation:
The process of photosynthesis is exhibited by plants to make their own food. They trap the carbon dioxide and form organic food, that is, glucose in presence of sunlight. The process of photosynthesis uses the energy of sunlight and gives off oxygen as by-product. Hence, glucose (C6H12O6) and oxygen are the products of the process of photosynthesis.
Infants are born with some connections between brain cells. True or false.
Answer:
True
Explanation:
It has been found that during birth, a child possess several neurons as well as synapses. These synapses indicate the connection between the brain cells. During birth a child has 2500 synapses per neuron which indicate pre-established neuron connections. With a scale of 2500 synapses per neuron, a child’s brain has billion of neurons which start developing and deleting additional neurons as a normal part of brain development activity.
Yes, infants are born with some connections already established between their brain cells, which play key roles in learning and memory. As a person grows and learns, new connections are constantly formed.
Explanation:The statement, 'Infants are born with some connections between brain cells' is true. In fact, infants are born with all the neurons (brain cells) they will have in their lifetime and there are already some connections, or synapses, established. The connections between these cells play essential roles in learning, memory and overall cognitive functioning. However, the brain constantly forms new connections as a person experiences and learns new things throughout their lifespan. This is a process known as neuroplasticity.

Which species is most closely related to the origin moth species?
Answer: Lack of information
Explanation:
You need to give the full question with options to select. As I don't know the answer I can explain Species C 14 is wrong.
Here is the full question:
A scientist is trying to determine how closely related a moth species (Species Z) is to four other moth species (Species A, B, C, and D). He examined the DNA of each species and compared it to the study subject. He then created this table.
Species # of genetic differences
Species A 12
Species B 3
Species C 14
Species D 28
Which species is most closely related to the moth species (Species Z)?
- species A
- species B
- species C (X) Not the answer
- species D
Recent genetic studies have blurred the lines between moths and butterflies, showing that they may not have a true divergence. Moths like the Marbled emperor may share close relations with some butterfly species. The case of the peppered moth demonstrates industrial melanism and the dynamic nature of evolutionary processes within the Lepidoptera order.
Recent genetic studies suggest that moths (Sub-Order Heterocera) and butterflies (Sub-Order Rhopalocera) may not have a true divergence between them, as some species previously classified separately show close genetic relations. The Marbled emperor moth, for instance, which evokes the image of an owl, might be more closely related to certain butterfly species than to other moths. This information comes from a broader understanding of the phylogeny of insects, which is supported by cladograms showing evolutionary relationships.
The phenomenon known as industrial melanism further illustrates the adaptive nature of moths. The example of the peppered moth, Biston betularia, vividly demonstrates this. Before the Industrial Revolution in England, the typically light-patterned peppered moths blended in with lichen-covered trees, avoiding predation. With rising pollution, darker moths had an advantage, and their population numbers surged by the late 19th century. This real-time observation of a population's adaptive response points to shared evolutionary pressures and similarities within the Lepidoptera order, which encompasses both moths and butterflies.
The Punnett square for a non-freckled parent and a homozygous freckled parent is shown below. What is the probability that their children will have freckles? a 100% b 50% c 0% d 75%
F F
f Ff Ff
f Ff Ff
Answer:
Option A, [tex]100 \\[/tex]%
Explanation:
Let the allele for non freckled trait be represented by “f”
The allele for freckled trait be represented by “F”
Let us consider that freckled trait is dominant over the non – freckled trait.
The genotype for a non – freckled parent will be “ff”
The genotype for a homozygous freckled parent will be “FF”
When a cross is carried out between a non – freckled parent and a homozygous freckled parent , the following offsprings are produced –
f f
F Ff Ff
F Ff Ff
Thus, all the four offsprings have heterozygous genotype. Since we assumed that freckled trait is dominant over the non – freckled trait, all the offsprings would be freckled.
Thus, the probability of a child having freckles would be
[tex]\frac{4}{4} * 100\\= 100\\[/tex]%
Thus, option A is correct.
