Which family in the periodic table has metals that are usually harder than other metals?
Alkali metals
Alkaline earth metals
Lanthanide series
Transition metals
Answer:
Transition metals
Explanation:
The transition metals are usually harder than other metals such as the alkali metal, lanthanide series metals and the alkaline earthmetals.
The reason for this is because they have a stronger metallic bonding between their atom.
Hardness is a physical property which is attributed to intermolecular forces and the atomic arrangement
The transition metals are found in the d - block on the periodic table.
They have a d-orbirtal which confers extra electrons and higher degree of stability to the atom. The d-orbirtal provides more delocalized electrons for the metallic bonds formed.
Answer:
The answer is D), transition metals
Explanation:
I searched it up, and the only metal with hardness showing as a significant property was transition metals. I took the test, and transition metals is the answer. I also pulled this up on the internet:
Transition metals are hard which indicates the presence of covalent bonds. This happens because transition metals have unpaired d-electrons. The d-orbital which contains the unpaired electrons may overlap and form covalent bonds. Therefore, these transition metals are very hard.

Life has changed through the process of
Answer:
Life has changed through the process of evolution
Explanation:
Evolution is defined as a change in the proportion of traits of genes from one generation to the next
In a pedigree, a rare trait appears in both sexes with equal frequency, and each affected offspring has one affected parent. What is the most likely mode of inheritance?
Answer:
Autosomal dominant inheritance
Explanation:
The most likely mode of inheritance of the trait would be autosomal dominance.
In autosomal dominant inheritance, a dominant allele on a non-sex chromosome is responsible for its transmission across generations. Unlike autosomal recessive traits that require two recessive alleles for their transmission, only one dominant allele is required for autosomal dominant traits and the implication is that it appears in every generation and both males and females have an equal chance of inheriting such traits.
Hence, for a rare trait that appears in both sexes with the same frequency and each affected offspring has one affected parent, the most likely mode of inheritance would be autosomal dominance.

All the human are the reasons for global environmental change through a subset of proximate causes, which straightforwardly modify parts of the climate in manners that have worldwide impacts. We start this section by laying out and showing a way to deal with representing the major proximate reasons for worldwide change, and afterward continue to the more troublesome issue of clarifying them.
Different contextual analyses delineate the different ways human activities can add to global environmental change and give solid foundation to the more hypothetical conversation that follows. We have recognized explicit exploration needs all through that conversation.

(1 Point)
Arrow 1 represents nitrogen and arrow 2 is oxygen
Arrow 1 represents oxygen and arrow 2 is nitrogen
Arrow 1 represents oxygen and arrow 2 is carbon dioxide
Arrow 1 represents carbon dioxide and arrow 2 is oxygen
Answer: Arrow 1 is carbon dioxide, and arrow 2 is oxygen
Explanation: I got it right in a test.
Photosynthesis is the process of preparing food in the presence of sunlight, water, and carbon dioxide. The process is carried out by the plants and certain bacteria and algae.
The correct answer is:
Option D. Arrow 1 represents carbon dioxide and arrow 2 is oxygen
The mechanism of photosynthesis can be explained as:
Photosynthesis is the process in which light energy is converted into chemical energy. The plants use up carbon dioxide and water in the presence of sunlight to yield products. During photosynthesis, the plants yield oxygen as a by-product and produce a sugar molecule to be used as energy.
Thus, the plants use carbon dioxide and give out oxygen during photosynthesis.

Enter your answer in the provided box. Calculate the frequency of the genotype Aa from a population that is made up of the following numbers of individuals: 41 individuals with the genotype AA 23 individuals with the genotype Aa 28 individuals with the genotype aa frequency of individuals with genotype Aa g
Answer:
25% or 0.25
Explanation:
The frequency of the genotype Aa from the population can be calculated from the formula;
Frequency of Aa = number of individuals with Aa/total population
number of individuals with Aa genotype = 23
Total population = 41+23+28 = 92
Hence,
Frequency of Aa = 23/92 = 0.25 or 25%
Which image represents cytokinesis in a plant cell?
Answer:
D
Explanation:
gl (:
A crucial function of cytokinesis is to divide the cell in half and make sure that one nucleus is placed in each daughter cell. Thus, option D is correct.
What is the importance of cytokinesis in plant cells?The four steps of cytokinesis are membrane insertion, contraction, and completion. Animal and plant cells experience these stages in different ways.
The assembly and action of an actomyosin-based contractile ring during animal cytokinesis were characterized as occurring at the cell periphery.
In contrast, it was thought that plant cell cytokinesis involved the centrifugal formation of a new cell wall through the fusion of vesicles generated from the Golgi apparatus.
Therefore, The process of cytokinesis begins at the anaphase phase of nuclear division and lasts until telophase.
