within the cell.
Answer: The Golgi apparatus modifies, packages, and sorts proteins for secretion or use within the cell
Explanation:
The Golgi apparatus modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell. The Golgi apparatus is found close to the nucleus of the cell where it modifies proteins that have been delivered in transport vesicles from the RER.

During meiosis, a process known as crossing over occurs. Which statement below summarizes the results of crossing over?
O Homologous chromosomes make copies of each other.
Genetic information is removed from both chromosomes.
O DNA winds up into chromosomes and genetic information is deleted.
O DNA is exchanged between homologous chromosomes, resulting in genetic variation.
Answer:the answers is B
Explanation:
Because reproduction occurs between homologous a chromosome
During meiosis, a process known as crossing over occurs. Genetic information is removed from both chromosomes.
What is meiosis ?Meiosis is the process where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.
Humans have 46 chromosomes in every cell, where 23 chromosomes t came from one of our parents and 23 very similar chromosomes that came from the other parents.
Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibres appear.
Secondly Prometaphase I where Spindle fibres attach to the centromere followed by Metaphase I where The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.
Telophase I where Spindle fibres disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells.

Sorry mate your question is very confusing
Do it again what is the question about
Answer:
B
Explanation:
The atom shown below is
A. likely to form a covalent bond
o B. likely to form an ionic bond
C. not likely to form any bonds
OD. likely to form double bonds
Answer:
C. Not Likely to form any bonds
Explanation:
Assuming this atom is of neutral charge, it would be neon. We can tell as it has 10 electrons total. 2 in the first shell, 8 in the second. Noble gasses do not form bonds, generally speaking.
Furthermore, any atom, ion or not, that has a full valance (outermost shell) is generally not likely to form bonds.
A male and a female, both with dimples, have a son without dimples. Which of Mendel's laws does this pattern of inheritance illustrate, and how do you know? AND What is the chance that a daughter of these parents would have dimples? Explain your answer.
Answer:
Explanation: Could you have drawn something different in question 3d? Explain. ... yes if both parents are heterozygous. 14 Chance no dimples. 1/4 dd 1/4 no ... If a woman is heterozygous for dimples and has 5 fingers, and a male is ... a Punnett square and calculate genotype and phenotype frequencies to explain your answer.
People also ask
According to the Mendel's Law of Segregation. Since, a male and a female, both with dimples, have a son without dimples which mean both the parents are heterozygous (Aa). since both are Aa × Aa there will be Aa, Aa, AA, aa. in which AA is dominant and aa is recessive thus the chance that a daughter of these parents would have dimple is 3/4.
What is Mendel's law of segregation?
Mendel's Law of Segregation states that a diploid organism passes a randomly selected allele for a trait to its offspring, such that the offspring receives one allele from each parent.
Thus, the chance that a daughter of these parents would have dimple is 3/4.

a. Shed their skin
b. shed their shells
C. continue cell reproduction
d. find larger shells to inhabit.
a.shed their skin..
Explanation:
Exoskeleton
A true exoskeleton, like that found in arthropods, must be shed (moulted) when it is outgrown. ... The new exoskeleton is still capable of growing to some degree, however. Animals of the order arthropoda, like lizards, amphibians, and many other animals that shed their skin, are indeterminate growers
Describe the relationship between the respiratory and circulatory systems and ATP. Use the term reactants in your response.
Answer:
Cellular respiration, which generates ATP in your cells, requires oxygen to take place, also, it generates CO2 as a waste product. The respiratory system allows oxygen to diffuse into your blood, and carbon dioxide to diffuse out. The blood then carries the oxygen to the cells, so cellular respiration to continue. When the blood reaches the cells, it also takes the carbon dioxide out of the cells, and carries it to the lungs to get rid of it.
How does human activity impact Earth's systems such as deforestation
urbanisation desertification, erosion, air and water quality, and
allemating the flow of water?**Please use full sentences ****
Answer: Land, Water,Urbanization, and smog and acid rain.
Explanation:
Smog and acid rain are produced through similar sources, primarily vehicle and industry emissions. Though both result from human-caused air pollutants, there are chemical distinctions between the two. Though there are regulations in effect to reduce both types of pollution, they remain a threat to both human health and the environment.Smog Causes A combination of three components -- nitrogen oxides, volatile organic compounds (VOCs) and sunlight -- causes smog. Nitrogen dioxide interacts with sunlight to create nitrogen oxide and a free oxygen molecule. This interaction produces ozone, which typically turns back into nitrogen dioxide, and the cycle repeats. The addition of VOCs interrupts the cycle, however. VOCs are produced by various sources, such as paint, cleaning products and refrigerants. The VOCs prevent the breakdown of ozone, allowing it to gather near the surface of the Earth, where even more nitric oxides are produced by vehicle and industry emissions, creating the dense smog seen in large cities such as Los Angeles and Beijing.Smog Hazards The presence of ozone in the form of smog can have several negative health effects. Respiratory systems can be irritated, reducing overall lung function and triggering asthma attacks. Evidence reported by the Environmental Protection Agency also suggests exposure to ozone reduces immune system responses, especially in the lungs. These effects subside over time, but little is known about the long-term effects of repeated exposure. Vegetation also suffers from smog, as plants that take up too much ozone can be damaged in ways such as discoloration and a loss of leaves that cuts photosynthesis efficiency by up to 50 percent.

the members of these kingdoms all have cell walls. Which kingdoms are they?
Answer:
kingdom plantae
Explanation:
members of this kingdom have a cell wall that gives their cells a box like structure
Organisms that belong to Kingdom Monera, Protista, Fungi, and Plantae all have cell walls.
What is a cell wall?The cell wall is the outermost covering of the cell which provides the cell with a rigid structure and protects it from the outside environment. It is present outside the plasma membrane.
The composition of the cell wall differs in different organisms. The cell wall in plants is composed of cellulose, hemicellulose, and pectin. In algae, the cell wall is composed of glycoproteins and polysaccharides.
Bacteria that belong to Kingdom Monera possess a cell wall composed of peptidoglycan while the organisms of Kingdom Fungi have a cell wall made up of chitin.
Therefore, organisms of the four kingdoms Monera, Protista, Fungi, and Plantae all possess a cell wall.

what is this data saying?
Answer:
Gene flow is the exchange of alleles between two or more populations. For this reason it is sometimes referred to as allele flow or gene migration. While migrating animals often carry new alleles from one population to another, they must interbreed with the new population for gene flow to occur. In the image below, a beetle from a population of brown beetles migrates into a population of green beetles.
