Answer:
u can find out The size of the seed
The correct answer is: B) flesh of another animal
The shape of teeth is tightly connected with the food that animal eats.Examples:
• Herbivores (plant eaters) have flat teeth specialized for the grass chewing.
• Carnivores (flesh eaters) have long and sharp teeth for meat cutting.
• Omnivores (eat meat and plants) such as humans have various types of teeth with different functions.
There are four main types of teeth: incisors (at the front, sharp for cutting), canines ( to grip and tear food), premolars (flat surface for food crushing), molars (the biggest with flat biting surface, to chew).
As each order of consumers eat other organisms, energy that transfers decreases.
Answer:
<em>The fungus can be transmitted through contact and the fungus is deadly to bats.</em>
Explanation:
David Blehert was a scientist who had received a PhD in the field of bacteriology.
David Blehert's hypothesis provided evidence that white-nose fungi were capable of causing death in bats. Even exposure of healthy bats to the bats which were infected with white-nose fungi caused illness and even death of the previously healthy bats.
David Blehert's hypothesis was also supported by other people who conducted the experiments and hence, was considered to be true.
Answer:
Sex Linkage
Explanation:
Sex linkage is the phenomenon in which the expression of genes depends on the gender of the organisms because genes for specific traits are located on the sex chromosomes of organisms.
What are sex chromosomes:
They are usually a pair of chromosomes present in higher organisms like humans and other mammals that combine during fertilization of male and female gametes and determine the sex of offspring. In humans they are X and Y chromosomes and when there is an XX offspring, she will e female and when there will be Xy offspring , he will be male.
Significance:
-
Now there are some genes that are present only on sex chromosomes of the organisms like genes for beard are present in human Y chromosome of men, However,genes found on the X chromosome can be found in either males or females.
- Sex linked genetic disorders are very common in human males because males receive only one copy of X chromosome while females receive two copies. So only one copy of defective gene is enough for the expression of disease in males while in women two copies are needed if the trait is recessive.
- For example: There is a disease called hemophilia in which the blood is unable to clot even after minor injuries and can be life threatening.
- Hemophilia is an X linked recessive disorder and is an example of sex linked traits controlled by sex linked genes.
Hope it helps!
